**Task:**
Generate a challenging test input that exposes the bug in the buggy code of the algorithm problem:
Algorithm Problem:
Title: Permutation Counting
time_limit_ms: 2000
memory_limit_mb: 256
Description: You have some cards. An integer between $1$ and $n$ is written on each card: specifically, for each $i$ from $1$ to $n$, you have $a_i$ cards which have the number $i$ written on them.

There is also a shop which contains unlimited cards of each type. You have $k$ coins, so you can buy $k$ new cards in total, and the cards you buy can contain any integer between $1$ and $n$.

After buying the new cards, you rearrange all your cards in a line. The score of a rearrangement is the number of (contiguous) subarrays of length $n$ which are a permutation of $[1, 2, \ldots, n]$. What's the maximum score you can get?

Input: Each test contains multiple test cases. The first line contains the number of test cases $t\ (1\le t\le 100)$. The description of the test cases follows.

The first line of each test case contains two integers $n$, $k$ ($1\le n \le 2 \cdot 10^5$, $0\le k \le 10^{12}$) — the number of distinct types of cards and the number of coins.

The second line of each test case contains $n$ integers $a_1, a_2, \ldots, a_n$ ($1 \le a_i \le 10^{12}$) — the number of cards of type $i$ you have at the beginning.

It is guaranteed that the sum of $n$ over all test cases does not exceed $5 \cdot 10^5$.

Output: For each test case, output a single line containing an integer: the maximum score you can get.

Examples:
input:
8
1 10
1
2 4
8 4
3 4
6 1 8
3 9
7 6 2
5 3
6 6 7 4 6
9 7
7 6 1 7 6 2 4 3 3
10 10
1 3 1 2 1 9 3 5 7 5
9 8
5 8 7 5 1 3 2 9 8
output:
11
15
15
22
28
32
28
36

Note: In the first test case, the final (and only) array we can get is $[1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]$ (including $11$ single $1$s), which contains $11$ subarrays consisting of a permutation of $[1]$.

In the second test case, we can buy $0$ cards of type $1$ and $4$ cards of type $2$, and then we rearrange the cards as following: $[1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2]$. There are $8$ subarrays equal to $[1, 2]$ and $7$ subarrays equal to $[2, 1]$, which make a total of $15$ subarrays which are a permutation of $[1, 2]$. It can also be proved that this is the maximum score we can get.

In the third test case, one of the possible optimal rearrangements is $[3, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 3]$.

**Instructions:**
- Focus on edge cases or scenarios that maximize the failure probability in faulty solutions.
- Due to the output length limit, you should generate a **small-scale** test input that is **complete and valid**.
- Output the test input directly, not code to generate it.

**Output format:**
```plaintext
{test input}
```

Think step by step.

Response:
To generate a challenging test input that exposes the bug in the provided buggy code, we need to focus on edge cases and scenarios that can cause the algorithm to fail. Here are some potential scenarios to consider:

1. **Large Values for `k` and `n`**: The code might have issues handling large values of `k` and `n`.
2. **Uneven Distribution of Cards**: The code might not handle cases where the initial distribution of cards is highly uneven.
3. **Small Values for `k` and `n`**: The code might have issues with small values, especially when `k` is 0.
4. **Edge Cases for `k` and `n`**: The code might fail when `k` is just enough to make a significant difference or when `n` is very small.

Let's create a small-scale test input that includes a mix of these scenarios:

```plaintext
5
1 10
1
2 4
8 4
3 4
6 1 8
3 9
7 6 2
5 3
6 6 7 4 6
```

This test input includes:
1. A case with `n = 1` and a large `k`.
2. A case with `n = 2` and a moderate `k`.
3. A case with `n = 3` and a moderate `k`, with an uneven distribution of cards.
4. A case with `n = 3` and a large `k`, with an uneven distribution of cards.
5. A case with `n = 5` and a small `k`, with a more even distribution of cards.

These scenarios should help in exposing any bugs in the algorithm.

Description: You have some cards. An integer between $1$ and $n$ is written on each card: specifically, for each $i$ from $1$ to $n$, you have $a_i$ cards which have the number $i$ written on them.

There is also a shop which contains unlimited cards of each type. You have $k$ coins, so you can buy $k$ new cards in total, and the cards you buy can contain any integer between $1$ and $n$.

After buying the new cards, you rearrange all your cards in a line. The score of a rearrangement is the number of (contiguous) subarrays of length $n$ which are a permutation of $[1, 2, \ldots, n]$. What's the maximum score you can get?

Input: Each test contains multiple test cases. The first line contains the number of test cases $t\ (1\le t\le 100)$. The description of the test cases follows.

The first line of each test case contains two integers $n$, $k$ ($1\le n \le 2 \cdot 10^5$, $0\le k \le 10^{12}$) — the number of distinct types of cards and the number of coins.

The second line of each test case contains $n$ integers $a_1, a_2, \ldots, a_n$ ($1 \le a_i \le 10^{12}$) — the number of cards of type $i$ you have at the beginning.

It is guaranteed that the sum of $n$ over all test cases does not exceed $5 \cdot 10^5$.

Output: For each test case, output a single line containing an integer: the maximum score you can get.

Examples:

output:

Note: In the first test case, the final (and only) array we can get is $[1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]$ (including $11$ single $1$s), which contains $11$ subarrays consisting of a permutation of $[1]$.

In the second test case, we can buy $0$ cards of type $1$ and $4$ cards of type $2$, and then we rearrange the cards as following: $[1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2]$. There are $8$ subarrays equal to $[1, 2]$ and $7$ subarrays equal to $[2, 1]$, which make a total of $15$ subarrays which are a permutation of $[1, 2]$. It can also be proved that this is the maximum score we can get.

In the third test case, one of the possible optimal rearrangements is $[3, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 3]$.

Algorithm Problem:
Title: Digital Village (Hard Version)
time_limit_ms: 2000
memory_limit_mb: 256
Description: This is the hard version of the problem. In the three versions, the constraints on $n$ and $m$ are different. You can make hacks only if all the versions of the problem are solved.

Pak Chanek is setting up internet connections for the village of Khuntien. The village can be represented as a connected simple graph with $n$ houses and $m$ internet cables connecting house $u_i$ and house $v_i$, each with a latency of $w_i$.

There are $p$ houses that require internet. Pak Chanek can install servers in at most $k$ of the houses. The houses that need internet will then be connected to one of the servers. However, since each cable has its latency, the latency experienced by house $s_i$ requiring internet will be the maximum latency of the cables between that house and the server it is connected to.

For each $k = 1,2,\ldots,n$, help Pak Chanek determine the minimum total latency that can be achieved for all the houses requiring internet.

Input: Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 2000$). The description of the test cases follows.

The first line of each test case contains three integers $n$, $m$, $p$ ($2 \le n \le 5000$; $n-1 \le m \le 5000$; $1 \le p \le n$) — the number of houses, the number of cables, and the number of houses that need internet.

The second line of each test case contains $p$ integers $s_1, s_2, \ldots, s_p$ ($1 \le s_i \le n$) — the houses that need internet. It is guaranteed that all elements of $s$ are distinct.

The $i$-th of the next $m$ lines of each test case contains three integers $u_i$, $v_i$, and $w_i$ ($1 \le u_i < v_i \le n$; $1 \le w_i \le 10^9$) — the internet cable connecting house $u_i$ and house $v_i$ with latency of $w_i$. It is guaranteed that the given edges form a connected simple graph.

It is guaranteed that the sum of $n$ and the sum of $m$ do not exceed $5000$.

Output: For each test case, output $n$ integers: the minimum total latency that can be achieved for all the houses requiring internet for each $k = 1,2,\ldots,n$.

Examples:
input:
2
9 8 5
2 5 6 8 9
1 2 1
1 3 2
3 4 10
4 5 3

1 7 10
7 8 4
7 9 2
3 3 2
3 1
1 2 1
2 3 3
1 3 2
output:
34 19 9 4 0 0 0 0 0
2 0 0

Note: In the first test case for $k=3$, a possible optimal solution is to install servers at vertices $2$, $6$ and $8$ and obtain the following latency:

  * $\text{latency}(2) = 0$    * $\text{latency}(5) = \max(3, 5) = 5$    * $\text{latency}(6) = 0$    * $\text{latency}(8) = 0$    * $\text{latency}(9) = \max(2, 4) = 4$

So the total latency is $9$.

**Instructions:**
- Focus on edge cases or scenarios that maximize the failure probability in faulty solutions.
- Due to the output length limit, you should generate a **small-scale** test input that is **complete and valid**.
- Output the test input directly, not code to generate it.

**Output format:**
```plaintext
{test input}
```

Think step by step.

Response:
To generate a challenging test input for the given algorithm problem, we need to focus on edge cases and scenarios that can expose potential bugs in the code. Here are the steps to consider:

1. **Simple Connected Graph**: Ensure the graph is connected, as the problem statement guarantees it.
2. **Small Scale**: Keep the number of houses and cables small to ensure the test case is manageable.
3. **House Requirements**: Include houses that require internet in a way that maximizes the difficulty of the problem.
4. **Latency Values**: Use latency values that can create interesting scenarios for the algorithm.

Let's construct a test case step by step:

1. **Number of Test Cases**: Set to 1 for simplicity.
2. **Number of Houses and Cables**: Choose a small number, e.g., \( n = 5 \) and \( m = 4 \).
3. **Houses Requiring Internet**: Choose a subset of houses that need internet, e.g., \( p = 3 \).
4. **Cable Connections and Latencies**: Ensure the graph is connected and the latencies are varied.

Here is the test input:

```plaintext
1
5 4 3
1 3 5
1 2 1
2 3 2
3 4 3
4 5 4
```

Explanation:
- **Test Case 1**: There is one test case.
- **5 Houses and 4 Cables**: The graph is connected with 5 houses and 4 cables.
- **3 Houses Requiring Internet**: Houses 1, 3, and 5 require internet.
- **Cable Connections and Latencies**:
  - House 1 is connected to House 2 with latency 1.
  - House 2 is connected to House 3 with latency 2.
  - House 3 is connected to House 4 with latency 3.
  - House 4 is connected to House 5 with latency 4.

This test case is designed to be small and manageable while still presenting a challenge to the algorithm. The latencies are increasing, which can help expose issues with how the algorithm handles different latency values and the selection of servers.


**Task:**
Generate a challenging test input that exposes the bug in the buggy code of the algorithm problem:
Algorithm Problem:
Title: Digital Village (Hard Version)
time_limit_ms: 2000
memory_limit_mb: 256
Description: This is the hard version of the problem. In the three versions, the constraints on $n$ and $m$ are different. You can make hacks only if all the versions of the problem are solved.

Pak Chanek is setting up internet connections for the village of Khuntien. The village can be represented as a connected simple graph with $n$ houses and $m$ internet cables connecting house $u_i$ and house $v_i$, each with a latency of $w_i$.

There are $p$ houses that require internet. Pak Chanek can install servers in at most $k$ of the houses. The houses that need internet will then be connected to one of the servers. However, since each cable has its latency, the latency experienced by house $s_i$ requiring internet will be the maximum latency of the cables between that house and the server it is connected to.

For each $k = 1,2,\ldots,n$, help Pak Chanek determine the minimum total latency that can be achieved for all the houses requiring internet.

Input: Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 2000$). The description of the test cases follows.

The first line of each test case contains three integers $n$, $m$, $p$ ($2 \le n \le 5000$; $n-1 \le m \le 5000$; $1 \le p \le n$) — the number of houses, the number of cables, and the number of houses that need internet.

The second line of each test case contains $p$ integers $s_1, s_2, \ldots, s_p$ ($1 \le s_i \le n$) — the houses that need internet. It is guaranteed that all elements of $s$ are distinct.

The $i$-th of the next $m$ lines of each test case contains three integers $u_i$, $v_i$, and $w_i$ ($1 \le u_i < v_i \le n$; $1 \le w_i \le 10^9$) — the internet cable connecting house $u_i$ and house $v_i$ with latency of $w_i$. It is guaranteed that the given edges form a connected simple graph.

It is guaranteed that the sum of $n$ and the sum of $m$ do not exceed $5000$.

Output: For each test case, output $n$ integers: the minimum total latency that can be achieved for all the houses requiring internet for each $k = 1,2,\ldots,n$.

Examples:
input:
2
9 8 5
2 5 6 8 9
1 2 1
1 3 2
3 4 10
4 5 3
4 6 5
1 7 10
7 8 4
7 9 2
3 3 2
3 1
1 2 1
2 3 3
1 3 2
output:
34 19 9 4 0 0 0 0 0
2 0 0

Note: In the first test case for $k=3$, a possible optimal solution is to install servers at vertices $2$, $6$ and $8$ and obtain the following latency:

  * $\text{latency}(2) = 0$    * $\text{latency}(5) = \max(3, 5) = 5$    * $\text{latency}(6) = 0$    * $\text{latency}(8) = 0$    * $\text{latency}(9) = \max(2, 4) = 4$

So the total latency is $9$.

```

Think step by step.

Response:
To generate a challenging test input that exposes the bug in the provided buggy code, we need to focus on edge cases and scenarios that can maximize the failure probability. Here are the steps to think through this:

1. **Understand the Bug**: The provided code uses a union-find data structure to manage the connected components and a dynamic programming approach to calculate the minimum total latency. The bug might be in how it handles the merging of components and the dynamic programming transitions.

2. **Edge Cases**:
   - **Single Component**: A graph where all houses are connected in a single component.
   - **Multiple Components**: A graph with multiple connected components.
   - **High Latency Edges**: Edges with very high latency to see if the algorithm correctly handles high latency scenarios.
   - **Multiple Servers**: Scenarios where the number of servers \( k \) is greater than or equal to the number of houses requiring internet.

3. **Challenging Scenarios**:
   - **Linear Graph**: A linear graph where each house is connected to the next one with varying latencies.
   - **Complete Graph**: A complete graph where every house is connected to every other house with varying latencies.
   - **Tree Structure**: A tree structure with a specific pattern of latencies.

Given the constraints and the need for a small-scale test input, let's focus on a linear graph with varying latencies and a complete graph with high latencies.

### Test Input

1 2 1
2 3 100
3 4 1
4 1 100
```

### Explanation
1. **First Test Case**:
   - **Graph**: A linear graph with 5 houses and 4 edges.
   - **Houses Requiring Internet**: 1, 3, 5.
   - **Edges**:
     - 1-2 with latency 1
     - 2-3 with latency 2
     - 3-4 with latency 3
     - 4-5 with latency 4
   - **Expected Output**: The algorithm should correctly handle the linear structure and calculate the minimum total latency for each \( k \).

2. **Second Test Case**:
   - **Graph**: A complete graph with 4 houses and 6 edges.
   - **Houses Requiring Internet**: 1, 2, 3.
   - **Edges**:
     - 1-2 with latency 1
     - 2-3 with latency 100
     - 3-4 with latency 1
     - 4-1 with latency 100
     - 1-3 with latency 1
     - 2-4 with latency 1
   - **Expected Output**: The algorithm should correctly handle the high latency edges and find the optimal placement of servers to minimize the total latency.

This test input is designed to challenge the algorithm by testing its ability to handle linear and complete graph structures with varying latencies.

**Task:**
Generate a challenging test input that exposes the bug in the buggy code of the algorithm problem:
Algorithm Problem:
Title: Digital Village (Hard Version)
time_limit_ms: 2000
memory_limit_mb: 256
Description: This is the hard version of the problem. In the three versions, the constraints on $n$ and $m$ are different. You can make hacks only if all the versions of the problem are solved.

Pak Chanek is setting up internet connections for the village of Khuntien. The village can be represented as a connected simple graph with $n$ houses and $m$ internet cables connecting house $u_i$ and house $v_i$, each with a latency of $w_i$.

There are $p$ houses that require internet. Pak Chanek can install servers in at most $k$ of the houses. The houses that need internet will then be connected to one of the servers. However, since each cable has its latency, the latency experienced by house $s_i$ requiring internet will be the maximum latency of the cables between that house and the server it is connected to.

For each $k = 1,2,\ldots,n$, help Pak Chanek determine the minimum total latency that can be achieved for all the houses requiring internet.

Input: Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 2000$). The description of the test cases follows.

The first line of each test case contains three integers $n$, $m$, $p$ ($2 \le n \le 5000$; $n-1 \le m \le 5000$; $1 \le p \le n$) — the number of houses, the number of cables, and the number of houses that need internet.

The second line of each test case contains $p$ integers $s_1, s_2, \ldots, s_p$ ($1 \le s_i \le n$) — the houses that need internet. It is guaranteed that all elements of $s$ are distinct.

The $i$-th of the next $m$ lines of each test case contains three integers $u_i$, $v_i$, and $w_i$ ($1 \le u_i < v_i \le n$; $1 \le w_i \le 10^9$) — the internet cable connecting house $u_i$ and house $v_i$ with latency of $w_i$. It is guaranteed that the given edges form a connected simple graph.

It is guaranteed that the sum of $n$ and the sum of $m$ do not exceed $5000$.

Output: For each test case, output $n$ integers: the minimum total latency that can be achieved for all the houses requiring internet for each $k = 1,2,\ldots,n$.

Examples:
input:
2
9 8 5
2 5 6 8 9
1 2 1
1 3 2
3 4 10
4 5 3
4 6 5
1 7 10
7 8 4
7 9 2
3 3 2
3 1
1 2 1
2 3 3
1 3 2
output:
34 19 9 4 0 0 0 0 0
2 0 0

Note: In the first test case for $k=3$, a possible optimal solution is to install servers at vertices $2$, $6$ and $8$ and obtain the following latency:

  * $\text{latency}(2) = 0$    * $\text{latency}(5) = \max(3, 5) = 5$    * $\text{latency}(6) = 0$    * $\text{latency}(8) = 0$    * $\text{latency}(9) = \max(2, 4) = 4$

So the total latency is $9$.

**Instructions:**
- Focus on edge cases or scenarios that maximize the failure probability in faulty solutions.
- Due to the output length limit, you should generate a **small-scale** test input that is **complete and valid**.
- Output the test input directly, not code to generate it.

**Output format:**
```plaintext
{test input}
```

Think step by step.

Response:
To create a challenging test input that exposes the bug in the provided code, we need to consider the following aspects:

1. **Graph Structure**: The graph should be connected and should have a structure that can expose issues with the DSU (Disjoint Set Union) and the priority queue handling.
2. **Edge Cases**: The test case should include scenarios where the algorithm might fail, such as:
   - A linear chain of nodes.
   - A star graph with a central node connected to all other nodes.
   - A graph with multiple cycles.
   - A graph where the required houses are not directly connected to each other.
3. **Constraints**: The test case should respect the constraints on \( n \), \( m \), and \( p \).

Given these considerations, let's create a small-scale test input that is complete and valid:

```plaintext
1
6 7 3
1 3 5
1 2 10
1 3 5
2 4 1
2 5 2
3 6 3
4 5 4
```

### Explanation:
- **Test Case Count**: 1
- **Number of Houses (n)**: 6
- **Number of Cables (m)**: 7
- **Number of Houses Requiring Internet (p)**: 3
- **Houses Requiring Internet**: 1, 3, 5
- **Edges**:
  - (1, 2, 10)
  - (1, 3, 5)
  - (2, 4, 1)
  - (2, 5, 2)
  - (3, 6, 3)
  - (4, 5, 4)

### Why This Test Input?
- **Graph Structure**: The graph is connected and has a mix of short and long edges, which can test the algorithm's ability to handle different latencies.
- **Edge Cases**:
  - House 1 and House 3 are connected directly, but House 5 is not directly connected to either of them.
  - The path from House 1 to House 5 involves a high-latency edge (10), while the path from House 3 to House 5 involves a lower-latency edge (3).
- **Constraints**: The test case is small enough to be manageable and respects the constraints \( 2 \le n \le 5000 \), \( n-1 \le m \le 5000 \), and \( 1 \le p \le n \).

This test input should help in exposing any bugs in the provided code, particularly in how it handles the DSU and the priority queue.

Description: This is the hard version of the problem. In the three versions, the constraints on $n$ and $m$ are different. You can make hacks only if all the versions of the problem are solved.

Pak Chanek is setting up internet connections for the village of Khuntien. The village can be represented as a connected simple graph with $n$ houses and $m$ internet cables connecting house $u_i$ and house $v_i$, each with a latency of $w_i$.

There are $p$ houses that require internet. Pak Chanek can install servers in at most $k$ of the houses. The houses that need internet will then be connected to one of the servers. However, since each cable has its latency, the latency experienced by house $s_i$ requiring internet will be the maximum latency of the cables between that house and the server it is connected to.

For each $k = 1,2,\ldots,n$, help Pak Chanek determine the minimum total latency that can be achieved for all the houses requiring internet.

Input: Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 2000$). The description of the test cases follows.

The first line of each test case contains three integers $n$, $m$, $p$ ($2 \le n \le 5000$; $n-1 \le m \le 5000$; $1 \le p \le n$) — the number of houses, the number of cables, and the number of houses that need internet.

The second line of each test case contains $p$ integers $s_1, s_2, \ldots, s_p$ ($1 \le s_i \le n$) — the houses that need internet. It is guaranteed that all elements of $s$ are distinct.

The $i$-th of the next $m$ lines of each test case contains three integers $u_i$, $v_i$, and $w_i$ ($1 \le u_i < v_i \le n$; $1 \le w_i \le 10^9$) — the internet cable connecting house $u_i$ and house $v_i$ with latency of $w_i$. It is guaranteed that the given edges form a connected simple graph.

It is guaranteed that the sum of $n$ and the sum of $m$ do not exceed $5000$.

Output: For each test case, output $n$ integers: the minimum total latency that can be achieved for all the houses requiring internet for each $k = 1,2,\ldots,n$.

Examples:
input:

1 3 2
output:
34 19 9 4 0 0 0 0 0
2 0 0

Note: In the first test case for $k=3$, a possible optimal solution is to install servers at vertices $2$, $6$ and $8$ and obtain the following latency:

  * $\text{latency}(2) = 0$    * $\text{latency}(5) = \max(3, 5) = 5$    * $\text{latency}(6) = 0$    * $\text{latency}(8) = 0$    * $\text{latency}(9) = \max(2, 4) = 4$

So the total latency is $9$.

Algorithm Problem:
Title: Digital Village (Hard Version)
time_limit_ms: 2000
memory_limit_mb: 256
Description: This is the hard version of the problem. In the three versions, the constraints on $n$ and $m$ are different. You can make hacks only if all the versions of the problem are solved.

Pak Chanek is setting up internet connections for the village of Khuntien. The village can be represented as a connected simple graph with $n$ houses and $m$ internet cables connecting house $u_i$ and house $v_i$, each with a latency of $w_i$.

There are $p$ houses that require internet. Pak Chanek can install servers in at most $k$ of the houses. The houses that need internet will then be connected to one of the servers. However, since each cable has its latency, the latency experienced by house $s_i$ requiring internet will be the maximum latency of the cables between that house and the server it is connected to.

For each $k = 1,2,\ldots,n$, help Pak Chanek determine the minimum total latency that can be achieved for all the houses requiring internet.

Input: Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 2000$). The description of the test cases follows.

The first line of each test case contains three integers $n$, $m$, $p$ ($2 \le n \le 5000$; $n-1 \le m \le 5000$; $1 \le p \le n$) — the number of houses, the number of cables, and the number of houses that need internet.

The second line of each test case contains $p$ integers $s_1, s_2, \ldots, s_p$ ($1 \le s_i \le n$) — the houses that need internet. It is guaranteed that all elements of $s$ are distinct.

The $i$-th of the next $m$ lines of each test case contains three integers $u_i$, $v_i$, and $w_i$ ($1 \le u_i < v_i \le n$; $1 \le w_i \le 10^9$) — the internet cable connecting house $u_i$ and house $v_i$ with latency of $w_i$. It is guaranteed that the given edges form a connected simple graph.

It is guaranteed that the sum of $n$ and the sum of $m$ do not exceed $5000$.

Output: For each test case, output $n$ integers: the minimum total latency that can be achieved for all the houses requiring internet for each $k = 1,2,\ldots,n$.

Examples:
input:
2
9 8 5
2 5 6 8 9
1 2 1
1 3 2
3 4 10
4 5 3
4 6 5
1 7 10
7 8 4
7 9 2
3 3 2
3 1
1 2 1
2 3 3
1 3 2
output:
34 19 9 4 0 0 0 0 0
2 0 0

Note: In the first test case for $k=3$, a possible optimal solution is to install servers at vertices $2$, $6$ and $8$ and obtain the following latency:

  * $\text{latency}(2) = 0$    * $\text{latency}(5) = \max(3, 5) = 5$    * $\text{latency}(6) = 0$    * $\text{latency}(8) = 0$    * $\text{latency}(9) = \max(2, 4) = 4$

So the total latency is $9$.

- Output the test input directly, not code to generate it.

**Output format:**
```plaintext
{test input}
```

Think step by step.

Response:
To generate a challenging test input that exposes the bug in the given code, we need to focus on edge cases or scenarios that can highlight issues in the algorithm. Here are the steps to think about the test input:

1. **Small Scale**: The input should be small enough to fit within the constraints but large enough to test the logic thoroughly.
2. **Edge Cases**: Consider cases where the graph is a tree, or where there are specific patterns in the connections and latencies.
3. **Critical Scenarios**: Test scenarios where the algorithm might fail to correctly compute the minimum total latency, such as when the houses requiring internet are not directly connected to the servers.

Let's construct a test case that fits these criteria:

- **Test Case 1**: A simple connected graph where the houses requiring internet are not directly connected to the servers.
- **Test Case 2**: A tree structure where the latencies are not uniformly distributed.

Here is a small-scale test input that fits these criteria:

```plaintext
2
6 5 4
1 3 5 6
1 2 1
2 3 2
3 4 3
4 5 4
5 6 5
4 3 2
1 2 1
2 3 2
3 4 3
```

### Explanation:
- **Test Case 1**:
  - **Graph**: A simple path graph with 6 nodes and 5 edges.
  - **Houses requiring internet**: 1, 3, 5, 6.
  - **Latencies**: The latencies increase as the distance from node 1 increases.
  - **Expected Output**: The optimal solution should place servers in such a way to minimize the total latency for the houses requiring internet.

- **Test Case 2**:
  - **Graph**: A simple path graph with 4 nodes and 3 edges.
  - **Houses requiring internet**: 1, 2.
  - **Latencies**: The latencies increase as the distance from node 1 increases.
  - **Expected Output**: The optimal solution should place servers in such a way to minimize the total latency for the houses requiring internet.

This test input will help expose any issues in the algorithm, especially in handling the placement of servers and computing the minimum total latency.

**Instructions:**
- Focus on edge cases or scenarios that maximize the failure probability in faulty solutions.
- Due to the output length limit, you should generate a **small-scale** test input that is **complete and valid**.
- Output the test input directly, not code to generate it.

**Output format:**
```plaintext
{test input}
```

Think step by step.

Response:
To generate a challenging test input that exposes the bug in the given code, we need to consider edge cases and scenarios that can maximize the failure probability in the faulty solution. Here are the steps to think through the process:

1. **Identify Potential Bugs:**
   - The code uses a union-find data structure to manage the connectivity of the graph.
   - The code sorts the edges by their latency and then processes them.
   - The code uses a depth-first search (DFS) to compute the minimum latency.

2. **Consider Edge Cases:**
   - **Single Component:** The graph is connected, so we need to ensure the graph remains connected.
   - **Multiple Components:** This is not applicable since the graph is connected.
   - **High Latency Edges:** Edges with very high latency can cause issues if the algorithm does not handle them correctly.
   - **Low Latency Edges:** Edges with very low latency can also cause issues if the algorithm does not handle them correctly.
   - **Multiple Houses Requiring Internet:** The distribution of houses requiring internet can affect the results.

3. **Generate a Small-Scale Test Input:**
   - We will create a small graph with a few houses and cables.
   - We will ensure that the houses requiring internet are distributed in a way that can expose the bug.
   - We will include a mix of high and low latency edges.

Here is a small-scale test input that can be used to expose the bug:

```plaintext
1
5 4 3
1 3 5
1 2 10
2 3 1
3 4 1
4 5 10
```

### Explanation:
- **Number of Test Cases:** 1
- **Number of Houses (n):** 5
- **Number of Cables (m):** 4
- **Houses Requiring Internet (p):** 3
- **Houses Requiring Internet:** 1, 3, 5
- **Edges:**
  - House 1 to House 2 with latency 10
  - House 2 to House 3 with latency 1
  - House 3 to House 4 with latency 1
  - House 4 to House 5 with latency 10

This test input is designed to:
- Ensure the graph is connected.
- Include high and low latency edges.
- Distribute the houses requiring internet in a way that can challenge the algorithm.

By using this test input, we can observe how the algorithm handles the high and low latency edges and the distribution of houses requiring internet. This should help in identifying any issues in the faulty solution.

Algorithm Problem:
Title: Digital Village (Hard Version)
time_limit_ms: 2000
memory_limit_mb: 256
Description: This is the hard version of the problem. In the three versions, the constraints on $n$ and $m$ are different. You can make hacks only if all the versions of the problem are solved.

Pak Chanek is setting up internet connections for the village of Khuntien. The village can be represented as a connected simple graph with $n$ houses and $m$ internet cables connecting house $u_i$ and house $v_i$, each with a latency of $w_i$.

There are $p$ houses that require internet. Pak Chanek can install servers in at most $k$ of the houses. The houses that need internet will then be connected to one of the servers. However, since each cable has its latency, the latency experienced by house $s_i$ requiring internet will be the maximum latency of the cables between that house and the server it is connected to.

For each $k = 1,2,\ldots,n$, help Pak Chanek determine the minimum total latency that can be achieved for all the houses requiring internet.

Input: Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 2000$). The description of the test cases follows.

The first line of each test case contains three integers $n$, $m$, $p$ ($2 \le n \le 5000$; $n-1 \le m \le 5000$; $1 \le p \le n$) — the number of houses, the number of cables, and the number of houses that need internet.

The second line of each test case contains $p$ integers $s_1, s_2, \ldots, s_p$ ($1 \le s_i \le n$) — the houses that need internet. It is guaranteed that all elements of $s$ are distinct.

The $i$-th of the next $m$ lines of each test case contains three integers $u_i$, $v_i$, and $w_i$ ($1 \le u_i < v_i \le n$; $1 \le w_i \le 10^9$) — the internet cable connecting house $u_i$ and house $v_i$ with latency of $w_i$. It is guaranteed that the given edges form a connected simple graph.

It is guaranteed that the sum of $n$ and the sum of $m$ do not exceed $5000$.

Output: For each test case, output $n$ integers: the minimum total latency that can be achieved for all the houses requiring internet for each $k = 1,2,\ldots,n$.

Examples:
input:
2
9 8 5
2 5 6 8 9
1 2 1
1 3 2
3 4 10
4 5 3
4 6 5
1 7 10
7 8 4
7 9 2
3 3 2
3 1
1 2 1
2 3 3
1 3 2
output:
34 19 9 4 0 0 0 0 0
2 0 0

Note: In the first test case for $k=3$, a possible optimal solution is to install servers at vertices $2$, $6$ and $8$ and obtain the following latency:

  * $\text{latency}(2) = 0$    * $\text{latency}(5) = \max(3, 5) = 5$    * $\text{latency}(6) = 0$    * $\text{latency}(8) = 0$    * $\text{latency}(9) = \max(2, 4) = 4$

So the total latency is $9$.

- Output the test input directly, not code to generate it.

**Output format:**

```

Think step by step.

Response:
To create a challenging test input that exposes potential bugs in the provided code, we need to consider edge cases and scenarios that might cause the algorithm to fail. Here are some key points to consider:

1. **Graph Structure**:
   - A linear graph where each house is connected to only two others (except the endpoints).
   - A star graph where one central house is connected to all other houses.
   - A complete graph where every house is connected to every other house.

2. **Latency Values**:
   - Very high latency values to test the handling of large numbers.
   - Equal latency values to test the handling of uniform edge weights.
   - Zero latency values to test edge cases.

3. **House Requirements**:
   - All houses require internet.
   - Only a few houses require internet.
   - Houses that require internet are at the ends of the graph.

4. **Server Placement**:
   - Test cases where the optimal placement of servers is not immediately obvious.

Given these considerations, let's create a small-scale test input that is complete and valid:

```plaintext
1
5 4 3
1 3 5
1 2 10
2 3 20
3 4 30
4 5 40
```

### Explanation:
- **Test Case 1**:
  - **Number of houses (n)**: 5
  - **Number of cables (m)**: 4
  - **Number of houses that need internet (p)**: 3
  - **Houses that need internet**: 1, 3, 5
  - **Cables**:
    - House 1 to House 2 with latency 10
    - House 2 to House 3 with latency 20
    - House 3 to House 4 with latency 30
    - House 4 to House 5 with latency 40

This test case is designed to:
- **Linear Graph Structure**: The houses form a linear structure, which can test the algorithm's ability to handle a simple path.
- **Diverse Latency Values**: The latencies are increasing, which can test how the algorithm handles different weights.
- **Specific House Requirements**: Only houses 1, 3, and 5 require internet, which can test how the algorithm handles a subset of houses requiring internet.

This input should help expose any bugs in the provided code, especially in how it handles the placement of servers and the calculation of minimum total latency.

However, since each cable has its latency, the latency experienced by house $s_i$ requiring internet will be the maximum latency of the cables between that house and the server it is connected to.

For each $k = 1,2,\ldots,n$, help Pak Chanek determine the minimum total latency that can be achieved for all the houses requiring internet.

Input: Each test contains multiple test cases. The first line contains the number of test cases $t$ ($1 \le t \le 2000$). The description of the test cases follows.

The first line of each test case contains three integers $n$, $m$, $p$ ($2 \le n \le 5000$; $n-1 \le m \le 5000$; $1 \le p \le n$) — the number of houses, the number of cables, and the number of houses that need internet.

The second line of each test case contains $p$ integers $s_1, s_2, \ldots, s_p$ ($1 \le s_i \le n$) — the houses that need internet. It is guaranteed that all elements of $s$ are distinct.

The $i$-th of the next $m$ lines of each test case contains three integers $u_i$, $v_i$, and $w_i$ ($1 \le u_i < v_i \le n$; $1 \le w_i \le 10^9$) — the internet cable connecting house $u_i$ and house $v_i$ with latency of $w_i$. It is guaranteed that the given edges form a connected simple graph.

It is guaranteed that the sum of $n$ and the sum of $m$ do not exceed $5000$.

Output: For each test case, output $n$ integers: the minimum total latency that can be achieved for all the houses requiring internet for each $k = 1,2,\ldots,n$.

output:

2 0 0

Note: In the first test case for $k=3$, a possible optimal solution is to install servers at vertices $2$, $6$ and $8$ and obtain the following latency:

So the total latency is $9$.

Think step by step.

Response:
To expose the bug in the provided code, we need to create a test case that highlights potential issues in the algorithm's logic. Here are the steps to think through the test case:

1. **Understand the Algorithm's Logic**:
   - The code uses a union-find data structure to merge components.
   - It calculates the minimum latency for each number of servers from 1 to n.
   - It sorts the edges by weight and processes them in increasing order of latency.

2. **Identify Potential Issues**:
   - The code might have issues with handling components that have different latencies when merging.
   - The code might not correctly handle the case where the number of servers is less than the number of houses that need internet.

3. **Design the Test Case**:
   - Create a graph with a small number of houses and edges.
   - Ensure that the graph has multiple components with different latencies.
   - Include a scenario where the number of servers is less than the number of houses that need internet.

4. **Test Case**:
   - Use a small number of houses and edges to keep the test case simple and manageable.
   - Ensure the graph is connected and has multiple paths with different latencies.

Here is a small-scale test input that should expose the bug:

```plaintext

Explanation:

  - Houses: 1, 2, 3, 4
  - Edges: (1, 2, 10), (2, 3, 1), (3, 4, 5), (1, 4, 2)
  - Houses requiring internet: 1, 3, 4

- **Expected Output**:
  - For k = 1: The minimum total latency is 16 (10 + 5 + 1).
  - For k = 2: The minimum total latency is 6 (5 + 1).
  - For k = 3: The minimum total latency is 0 (0 + 0 + 0).
  - For k = 4: The minimum total latency is 0 (0 + 0 + 0).

This test case should help in identifying any issues with the algorithm's handling of different latencies and the merging of components.

**Instructions:**
- Focus on edge cases or scenarios that maximize the failure probability in faulty solutions.
- Due to the output length limit, you should generate a **small-scale** test input that is **complete and valid**.
- Output the test input directly, not code to generate it.

**Output format:**
```plaintext
{test input}
```

Think step by step.

Response:
