**Task:**
Generate a challenging test input that exposes the bug in the buggy code of the algorithm problem:
Algorithm Problem:
Title: Trinity
time_limit_ms: 2000
memory_limit_mb: 256
Description: You are given an array $a$ of $n$ elements $a_1, a_2, \ldots, a_n$.

You can perform the following operation any number (possibly $0$) of times:

  * Choose two integers $i$ and $j$, where $1 \le i, j \le n$, and assign $a_i := a_j$.

Find the minimum number of operations required to make the array $a$ satisfy the condition:

  * For every pairwise distinct triplet of indices $(x, y, z)$ ($1 \le x, y, z \le n$, $x \ne y$, $y \ne z$, $x \ne z$), there exists a non-degenerate triangle with side lengths $a_x$, $a_y$ and $a_z$, i.e. $a_x + a_y > a_z$, $a_y + a_z > a_x$ and $a_z + a_x > a_y$.

Input: Each test consists of multiple test cases. The first line contains a single integer $t$ ($1 \le t \le 10^4$) — the number of test cases. The description of the test cases follows.

The first line of each test case contains a single integer $n$ ($3 \le n \le 2 \cdot 10^5$) — the number of elements in the array $a$.

The second line of each test case contains $n$ integers $a_1, a_2, \ldots, a_n$ ($1 \le a_i \le 10^9$) — the elements of the array $a$.

It is guaranteed that the sum of $n$ over all test cases does not exceed $2 \cdot 10^5$.

Output: For each test case, output a single integer — the minimum number of operations required.

Examples:
input:
4
7
1 2 3 4 5 6 7
3
1 3 2

4 5 3
15
9 3 8 1 6 5 3 8 2 1 4 2 9 4 7
output:
3
1
0
8

Note: In the first test case, one of the possible series of operations would be:

  * Assign $a_1 := a_4 = 4$. The array will become $[4, 2, 3, 4, 5, 6, 7]$.    * Assign $a_2 := a_5 = 5$. The array will become $[4, 5, 3, 4, 5, 6, 7]$.    * Assign $a_7 := a_1 = 4$. The array will become $[4, 5, 3, 4, 5, 6, 4]$.

It can be proven that any triplet of elements with pairwise distinct indices in the final array forms a non-degenerate triangle, and there is no possible answer using less than $3$ operations.

In the second test case, we can assign $a_1 := a_2 = 3$ to make the array $a = [3, 3, 2]$.

In the third test case, since $3$, $4$ and $5$ are valid side lengths of a triangle, we don't need to perform any operation to the array.

Buggy Code:
from itertools import combinations
t=int(input())
l=[]
for i in range(0,t):
    n=int(input())
    l.append([int(x) for x in input().split(" ")])
for i in range(0,t):
    ar=l[i]
    n=len(ar)
    w=[1]*n
    for j in range(0,n):
        w[j]=j
    comb=list(combinations(w,2))
    nn=len(comb)
    c=2
    countt=999999999
    s=0.0
    #sarr=[0]*99999999
    #for j in range(0,99999999):
    #    sarr[j]=j
    #for x in ar:
    #    s=s+x
    #    sarr[x]=sarr[x]+1
    #s=s/n
    ar.sort(reverse=False)
    inc=0
    while inc<n-2 and ar[n-1]>=ar[inc]+ar[inc+1]:
        inc=inc+1
    c=c+1
    #print(ar)
    print(inc)

**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.

Response:
To create a challenging test input that exposes the bug in the provided buggy code, let's consider the following steps:

1. **Identify the Bug**: The buggy code seems to have issues with the logic for determining the minimum number of operations required. It uses a combination of indices and a while loop to incrementally check the array, but it does not correctly handle the conditions for forming a non-degenerate triangle.

2. **Edge Cases**: We need to consider edge cases where the array elements are such that the triangle inequality is not easily satisfied, and the number of operations required is non-trivial.

3. **Test Case Design**: We should design a test case with a small number of elements (to keep it small-scale) but with values that require multiple operations to satisfy the triangle inequality.

Let's create a test case with the following properties:
- The array has elements that are not immediately forming a valid triangle.
- The elements are such that the minimum number of operations required is more than 1.

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

```plaintext
4
7
1 2 3 4 5 6 10
3
1 2 3
3
1 1 1
10
1 1 2 3 5 8 13 21 34 55
```

Explanation:
- **Test Case 1**: The array `[1, 2, 3, 4, 5, 6, 10]` requires multiple operations to make all triplets form valid triangles. For example, `1 + 2 <= 10` does not form a valid triangle.
- **Test Case 2**: The array `[1, 2, 3]` requires 1 operation to make all triplets form valid triangles. For example, `1 + 2 <= 3` does not form a valid triangle.
- **Test Case 3**: The array `[1, 1, 1]` already forms valid triangles, so no operations are required.
- **Test Case 4**: The array `[1, 1, 2, 3, 5, 8, 13, 21, 34, 55]` requires multiple operations to make all triplets form valid triangles. For example, `1 + 1 <= 2` does not form a valid triangle.

This test input should help in identifying the issues in the buggy code.

Response:
To expose the bug in the given code, we need to create a test case that highlights the issue with the current logic. The current logic in the `solve` method checks if the sum of the two smallest elements is greater than the largest element. However, this approach is flawed because it only considers the largest element and does not ensure that all possible triplets in the array can form a non-degenerate triangle.

### Step-by-Step Reasoning:

1. **Identify the Bug**:
   - The current logic only checks if the sum of the two smallest elements is greater than the largest element.
   - This does not ensure that all triplets in the array can form a non-degenerate triangle.

2. **Create a Test Case**:
   - We need an array where the sum of the two smallest elements is less than the largest element, but there are other elements that can form valid triangles.
   - The goal is to make the code fail by not correctly identifying the minimum number of operations needed to make all triplets valid.

3. **Example Test Case**:
   - Consider an array where the smallest two elements are small, and the largest element is much larger.
   - For example, an array like `[1, 1, 100]`:
     - The sum of the two smallest elements is `1 + 1 = 2`, which is not greater than `100`.
     - However, we can make all elements equal to `100` in one operation, and then all triplets will form valid triangles.

### Test Input:
```plaintext
1
3
1 1 100
```

### Explanation:
- The array `[1, 1, 100]` has the property that the sum of the two smallest elements is less than the largest element.
- The current code will output `2` because it will increment `ans` twice before breaking.
- However, the correct answer is `1` because we can make all elements equal to `100` in one operation, and then all triplets will form valid triangles.

This test case should effectively expose the bug in the given code.

Response:
To expose the bug in the provided code, we need to focus on the logic that determines the minimum number of operations required. The code sorts the array and then iterates through it to find the point where the sum of the two smallest elements is greater than the largest element. However, this approach does not correctly handle all edge cases, especially those where the array has many distinct elements that need to be adjusted to form valid triangles.

### Key Points to Consider:
1. **Sorted Array and Triangle Inequality**: The code assumes that sorting the array and checking the sum of the two smallest elements against the largest element will determine the number of operations needed. This is incorrect because it does not account for the fact that multiple elements might need to be adjusted to form valid triangles.
2. **Edge Cases**: We need to test with arrays that have a large number of distinct elements, as well as arrays where the smallest elements are significantly smaller than the largest elements.

### Test Input:
We will create a test case with a small number of elements that highlights the issue. Consider an array where the smallest elements are much smaller than the largest element, and the array is such that it requires a significant number of operations to form valid triangles.

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

### Explanation:
- **Array**: `[1, 2, 3, 4, 10]`
- **Sorted Array**: `[1, 2, 3, 4, 10]`
- **Operations Needed**:
  - To form a valid triangle with the largest element `10`, we need to adjust the smaller elements.
  - For example, we can assign `a_1 := 5`, `a_2 := 5`, and `a_3 := 5` to make the array `[5, 5, 5, 4, 10]`.
  - This requires 3 operations.

The provided code will output `2` because it will stop at the first valid pair `(4, 10)` where `4 + 4 > 10`, which is incorrect. The correct output should be `3`.

This test case should expose the bug in the code.

**Task:**
Generate a challenging test input that exposes the bug in the buggy code of the algorithm problem:
Algorithm Problem:
Title: Trinity
time_limit_ms: 2000
memory_limit_mb: 256
Description: You are given an array $a$ of $n$ elements $a_1, a_2, \ldots, a_n$.

You can perform the following operation any number (possibly $0$) of times:

  * Choose two integers $i$ and $j$, where $1 \le i, j \le n$, and assign $a_i := a_j$.

Find the minimum number of operations required to make the array $a$ satisfy the condition:

  * For every pairwise distinct triplet of indices $(x, y, z)$ ($1 \le x, y, z \le n$, $x \ne y$, $y \ne z$, $x \ne z$), there exists a non-degenerate triangle with side lengths $a_x$, $a_y$ and $a_z$, i.e. $a_x + a_y > a_z$, $a_y + a_z > a_x$ and $a_z + a_x > a_y$.

Input: Each test consists of multiple test cases. The first line contains a single integer $t$ ($1 \le t \le 10^4$) — the number of test cases. The description of the test cases follows.

The first line of each test case contains a single integer $n$ ($3 \le n \le 2 \cdot 10^5$) — the number of elements in the array $a$.

The second line of each test case contains $n$ integers $a_1, a_2, \ldots, a_n$ ($1 \le a_i \le 10^9$) — the elements of the array $a$.

It is guaranteed that the sum of $n$ over all test cases does not exceed $2 \cdot 10^5$.

Output: For each test case, output a single integer — the minimum number of operations required.

Examples:
input:
4
7
1 2 3 4 5 6 7
3
1 3 2
3
4 5 3
15
9 3 8 1 6 5 3 8 2 1 4 2 9 4 7
output:
3
1
0
8

Note: In the first test case, one of the possible series of operations would be:

  * Assign $a_1 := a_4 = 4$. The array will become $[4, 2, 3, 4, 5, 6, 7]$.    * Assign $a_2 := a_5 = 5$. The array will become $[4, 5, 3, 4, 5, 6, 7]$.    * Assign $a_7 := a_1 = 4$. The array will become $[4, 5, 3, 4, 5, 6, 4]$.

It can be proven that any triplet of elements with pairwise distinct indices in the final array forms a non-degenerate triangle, and there is no possible answer using less than $3$ operations.

In the second test case, we can assign $a_1 := a_2 = 3$ to make the array $a = [3, 3, 2]$.

In the third test case, since $3$, $4$ and $5$ are valid side lengths of a triangle, we don't need to perform any operation to the array.

Buggy Code:
T = int(input())
for t in range(T):
    n = int(input())
    s = list(map(int, input().split()))
    s.sort()
    MOD = 10**9
    s[-1] %= MOD
    c = i = 0
    while i < len(s) - 2 and (s[i]%MOD) + (s[i + 1]%MOD) <= s[-1]:
        c += 1
        i += 1
    print(c)

**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

```

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 where the code's logic fails. The buggy code has the following issues:

1. It only checks the last element of the sorted array `s` against the sum of the two smallest elements.
2. It uses a modulus operation which is unnecessary and can introduce incorrect results.

Given these issues, we can create a test case where the array is such that the last element is significantly larger than the sum of the two smallest elements, but the other elements can still form valid triangles.

Here's a step-by-step approach to create such a test case:

1. **Choose a small number of test cases** to keep the input small and manageable.
2. **Create an array where the last element is much larger than the sum of the two smallest elements**.
3. **Ensure the rest of the elements can form valid triangles**.

Let's create a test case with 3 elements where the last element is significantly larger than the sum of the two smallest elements:

```plaintext
1
3
1 1 10
```

In this test case:
- The array is `[1, 1, 10]`.
- The sum of the two smallest elements is `1 + 1 = 2`.
- The last element is `10`, which is greater than `2`.
- The code will incorrectly output `1` because it only checks the last element against the sum of the two smallest elements.

This test case will expose the bug in the buggy code. Here is the test input:

```plaintext

1 1 10

You can perform the following operation any number (possibly $0$) of times:

  * Choose two integers $i$ and $j$, where $1 \le i, j \le n$, and assign $a_i := a_j$.

Find the minimum number of operations required to make the array $a$ satisfy the condition:

  * For every pairwise distinct triplet of indices $(x, y, z)$ ($1 \le x, y, z \le n$, $x \ne y$, $y \ne z$, $x \ne z$), there exists a non-degenerate triangle with side lengths $a_x$, $a_y$ and $a_z$, i.e. $a_x + a_y > a_z$, $a_y + a_z > a_x$ and $a_z + a_x > a_y$.

It can be proven that any triplet of elements with pairwise distinct indices in the final array forms a non-degenerate triangle, and there is no possible answer using less than $3$ operations.

In the second test case, we can assign $a_1 := a_2 = 3$ to make the array $a = [3, 3, 2]$.

In the third test case, since $3$, $4$ and $5$ are valid side lengths of a triangle, we don't need to perform any operation to the array.

Response:
To expose the bug in the given code, we need to create a test case that highlights the issue in the logic. The buggy code uses a simple approach to count the number of operations required to make the array satisfy the triangle inequality condition. However, it only considers the last element in the sorted array and checks if the sum of any two smaller elements is greater than the largest element. This approach is flawed because it doesn't account for all possible triplets in the array.

### Steps to Create the Test Case:
1. **Identify the Bug**: The bug lies in the assumption that only the largest element needs to be considered. The code fails to ensure that all triplets in the array satisfy the triangle inequality condition.

2. **Create a Test Case**:
   - **Small Scale**: The test case should be small enough to fit the output format but still expose the bug.
   - **Edge Case**: The array should be such that the sum of the two smallest elements is less than or equal to the largest element, but there are other elements that can form valid triangles.

### Example Test Case:
Consider an array where the sum of the two smallest elements is less than or equal to the largest element, but there are other elements that can form valid triangles. For example, an array where the first few elements are small, and the last few elements are large, but not all large elements are the same.

### Test Input:
```plaintext
1
5
1 1 2 3 4
```

### Explanation:
- **Array**: [1, 1, 2, 3, 4]
- **Sorted Array**: [1, 1, 2, 3, 4]
- **Buggy Code Logic**:
  - The code will check if `1 + 1 <= 4`, which is true.
  - It will increment the count and move to the next element.
  - The code will output `1` because it only considers the largest element and the sum of the two smallest elements.
- **Correct Solution**:
  - The correct number of operations required is `2`. We need to assign `a[0] = 3` and `a[1] = 3` to make the array `[3, 3, 2, 3, 4]`, which satisfies the triangle inequality for all triplets.

This test case should expose the bug in the given code by showing that the code's logic is insufficient to handle all possible triplets in the array.

To generate a challenging test input that exposes the bug in the given code, we need to consider the following points:

1. **Understanding the Bug**: The code calculates two values, `res1` and `res2`, and outputs the minimum of these two values. `res1` counts the number of elements that need to be changed to ensure the sum of the smallest two elements is greater than the largest element. `res2` counts the number of elements that need to be changed to ensure the sum of the smallest two elements is greater than any other element. The bug lies in the assumption that the minimum of these two values is always the correct answer.

2. **Edge Cases**: We need to create an input where the minimum of `res1` and `res2` is not the correct answer. This can happen if the array is already close to satisfying the triangle inequality for some elements but not others.

3. **Input Generation**: We will create an array where the sum of the smallest two elements is just slightly less than the largest element, and the rest of the elements are in a configuration that makes the problem more complex.

Let's create a test input that exposes this bug:

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

### Explanation:
- **Array**: `[1, 2, 3, 4, 10]`
- **Sorted Array**: `[1, 2, 3, 4, 10]`
- **res1 Calculation**:
  - `1 + 2 <= 10` (True, `res1 = 1`)
  - `1 + 3 <= 10` (True, `res1 = 2`)
  - `1 + 4 <= 10` (True, `res1 = 3`)
  - `2 + 3 <= 10` (True, `res1 = 4`)
  - `2 + 4 <= 10` (True, `res1 = 5`)
  - `3 + 4 <= 10` (True, `res1 = 6`)
  - Break because `3 + 4 > 10` is False.
- **res2 Calculation**:
  - `1 + 2 <= 10` (True, `res2 = 1`)
  - `1 + 2 <= 9` (True, `res2 = 2`)
  - `1 + 2 <= 8` (True, `res2 = 3`)
  - `1 + 2 <= 7` (True, `res2 = 4`)
  - `1 + 2 <= 6` (True, `res2 = 5`)
  - Break because `1 + 2 > 5` is False.

The correct answer for this test case is 2, but the code will output 1 because it takes the minimum of `res1` and `res2`, which is incorrect.

This test input should effectively expose the bug in the given code.

Algorithm Problem:
Title: Eliminating Balls With Merging (Hard Version)
time_limit_ms: 4000
memory_limit_mb: 512
Description: Drink water.

— Sun Tzu, The Art of Becoming a Healthy Programmer

This is the hard version of the problem. The only difference is that $x=1$ in this version. You must solve both versions to be able to hack.

You are given two integers $n$ and $x$ ($x=1$). There are $n$ balls lined up in a row, numbered from $1$ to $n$ from left to right. Initially, there is a value $a_i$ written on the $i$-th ball.

For each integer $i$ from $1$ to $n$, we define a function $f(i)$ as follows:

  * Suppose you have a set $S = \\{1, 2, \ldots, i\\}$.

  * In each operation, you have to select an integer $l$ ($1 \leq l < i$) from $S$ such that $l$ is not the largest element of $S$. Suppose $r$ is the smallest element in $S$ which is greater than $l$.

    * If $a_l > a_r$, you set $a_l = a_l + a_r$ and remove $r$ from $S$.      * If $a_l < a_r$, you set $a_r = a_l + a_r$ and remove $l$ from $S$.      * If $a_l = a_r$, you choose either the integer $l$ or $r$ to remove from $S$:        * If you choose to remove $l$ from $S$, you set $a_r = a_l + a_r$ and remove $l$ from $S$.        * If you choose to remove $r$ from $S$, you set $a_l = a_l + a_r$ and remove $r$ from $S$.

  * $f(i)$ denotes the number of integers $j$ ($1 \le j \le i$) such that it is possible to obtain $S = \\{j\\}$ after performing the above operations exactly $i - 1$ times.

For each integer $i$ from $x$ to $n$, you need to find $f(i)$.

Input: The first line contains $t$ ($1 \leq t \leq 10^4$) — the number of test cases.

The first line of each test case contains two integers $n$ and $x$ ($1 \leq n \leq 2 \cdot 10^5; x = 1$) — the number of balls and the smallest index $i$ for which you need to find $f(i)$.

The second line of each test case contains $a_1, a_2, \ldots, a_n$ ($1 \leq a_i \leq 10^9$) — the initial number written on each ball.

It is guaranteed that the sum of $n$ over all test cases does not exceed $2 \cdot 10^5$.

Output: For each test case, output $n-x+1$ space separated integers on a new line, where the $j$-th integer should represent $f(x+j-1)$.

Examples:
input:
3
5 1
1 2 3 2 1
7 1
4 5 1 2 1 4 5
11 1
1 2 3 1 1 9 3 2 4 1 3
output:
1 1 2 2 3
1 1 1 1 1 3 4
1 1 2 2 2 1 1 1 3 3 4

Note: In the first test case, below are the possible values of $j$ for each $f(i)$ from $1$ to $n$.

  * For $f(1)$, the only possible value of $j$ is $1$.    * For $f(2)$, the only possible value of $j$ is $2$.    * For $f(3)$, the possible values of $j$ are $2$ and $3$.    * For $f(4)$, the possible values of $j$ are $2$ and $3$.    * For $f(5)$, the possible values of $j$ are $2$, $3$, and $4$.

Think step by step.

Response:
To generate a challenging test input that exposes the bug in the provided buggy code, we need to consider edge cases and scenarios that maximize the failure probability. The key points to focus on are:

1. **Small-scale input**: The test case should be small enough to be manageable but complex enough to expose issues.
2. **Edge cases**: Consider sequences that have repeated values, sequences with large values, and sequences that test the boundary conditions.
3. **Boundary conditions**: Test the limits of the input constraints, such as the smallest and largest possible values for `n` and `a_i`.

Let's construct a test case that includes these elements:

- A sequence with repeated values to test the merging logic.
- A sequence with large values to test the sum and comparison logic.
- A sequence that tests the boundary conditions.

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

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

### Explanation:
- **Test Case 1**:
  - **n = 5**: The number of balls.
  - **x = 1**: The smallest index for which we need to find \( f(i) \).
  - **a = [1, 2, 2, 3, 1]**: The initial values on the balls.

### Why This Input is Challenging:
1. **Repeated Values**: The sequence contains repeated values (2, 2), which will test the merging logic and the handling of equal values.
2. **Boundary Conditions**: The sequence starts and ends with the smallest value (1), which will test the boundary conditions and the merging logic at the start and end of the sequence.
3. **Mixed Values**: The sequence has a mix of small and large values (1, 2, 3), which will test the sum and comparison logic.

This input should help expose any issues in the buggy code, particularly in how it handles repeated values and boundary conditions.

You are given two integers $n$ and $x$ ($x=1$). There are $n$ balls lined up in a row, numbered from $1$ to $n$ from left to right. Initially, there is a value $a_i$ written on the $i$-th ball.

For each integer $i$ from $1$ to $n$, we define a function $f(i)$ as follows:

  * Suppose you have a set $S = \\{1, 2, \ldots, i\\}$.

  * In each operation, you have to select an integer $l$ ($1 \leq l < i$) from $S$ such that $l$ is not the largest element of $S$. Suppose $r$ is the smallest element in $S$ which is greater than $l$.

    * If $a_l > a_r$, you set $a_l = a_l + a_r$ and remove $r$ from $S$.      * If $a_l < a_r$, you set $a_r = a_l + a_r$ and remove $l$ from $S$.      * If $a_l = a_r$, you choose either the integer $l$ or $r$ to remove from $S$:        * If you choose to remove $l$ from $S$, you set $a_r = a_l + a_r$ and remove $l$ from $S$.        * If you choose to remove $r$ from $S$, you set $a_l = a_l + a_r$ and remove $r$ from $S$.

  * $f(i)$ denotes the number of integers $j$ ($1 \le j \le i$) such that it is possible to obtain $S = \\{j\\}$ after performing the above operations exactly $i - 1$ times.

For each integer $i$ from $x$ to $n$, you need to find $f(i)$.

Input: The first line contains $t$ ($1 \leq t \leq 10^4$) — the number of test cases.

The first line of each test case contains two integers $n$ and $x$ ($1 \leq n \leq 2 \cdot 10^5; x = 1$) — the number of balls and the smallest index $i$ for which you need to find $f(i)$.

The second line of each test case contains $a_1, a_2, \ldots, a_n$ ($1 \leq a_i \leq 10^9$) — the initial number written on each ball.

It is guaranteed that the sum of $n$ over all test cases does not exceed $2 \cdot 10^5$.

Output: For each test case, output $n-x+1$ space separated integers on a new line, where the $j$-th integer should represent $f(x+j-1)$.

Examples:
input:

1 2 3 2 1

output:
1 1 2 2 3
1 1 1 1 1 3 4
1 1 2 2 2 1 1 1 3 3 4

Note: In the first test case, below are the possible values of $j$ for each $f(i)$ from $1$ to $n$.

  * For $f(1)$, the only possible value of $j$ is $1$.    * For $f(2)$, the only possible value of $j$ is $2$.    * For $f(3)$, the possible values of $j$ are $2$ and $3$.    * For $f(4)$, the possible values of $j$ are $2$ and $3$.    * For $f(5)$, the possible values of $j$ are $2$, $3$, and $4$.

Algorithm Problem:
Title: Eliminating Balls With Merging (Hard Version)

Description: Drink water.

— Sun Tzu, The Art of Becoming a Healthy Programmer

This is the hard version of the problem. The only difference is that $x=1$ in this version. You must solve both versions to be able to hack.

You are given two integers $n$ and $x$ ($x=1$). There are $n$ balls lined up in a row, numbered from $1$ to $n$ from left to right. Initially, there is a value $a_i$ written on the $i$-th ball.

For each integer $i$ from $1$ to $n$, we define a function $f(i)$ as follows:

  * Suppose you have a set $S = \\{1, 2, \ldots, i\\}$.

  * In each operation, you have to select an integer $l$ ($1 \leq l < i$) from $S$ such that $l$ is not the largest element of $S$. Suppose $r$ is the smallest element in $S$ which is greater than $l$.

    * If $a_l > a_r$, you set $a_l = a_l + a_r$ and remove $r$ from $S$.      * If $a_l < a_r$, you set $a_r = a_l + a_r$ and remove $l$ from $S$.      * If $a_l = a_r$, you choose either the integer $l$ or $r$ to remove from $S$:        * If you choose to remove $l$ from $S$, you set $a_r = a_l + a_r$ and remove $l$ from $S$.        * If you choose to remove $r$ from $S$, you set $a_l = a_l + a_r$ and remove $r$ from $S$.

  * $f(i)$ denotes the number of integers $j$ ($1 \le j \le i$) such that it is possible to obtain $S = \\{j\\}$ after performing the above operations exactly $i - 1$ times.

For each integer $i$ from $x$ to $n$, you need to find $f(i)$.

Input: The first line contains $t$ ($1 \leq t \leq 10^4$) — the number of test cases.

The first line of each test case contains two integers $n$ and $x$ ($1 \leq n \leq 2 \cdot 10^5; x = 1$) — the number of balls and the smallest index $i$ for which you need to find $f(i)$.

The second line of each test case contains $a_1, a_2, \ldots, a_n$ ($1 \leq a_i \leq 10^9$) — the initial number written on each ball.

It is guaranteed that the sum of $n$ over all test cases does not exceed $2 \cdot 10^5$.

Output: For each test case, output $n-x+1$ space separated integers on a new line, where the $j$-th integer should represent $f(x+j-1)$.

Examples:
input:
3
5 1
1 2 3 2 1
7 1
4 5 1 2 1 4 5
11 1
1 2 3 1 1 9 3 2 4 1 3
output:
1 1 2 2 3
1 1 1 1 1 3 4
1 1 2 2 2 1 1 1 3 3 4

Note: In the first test case, below are the possible values of $j$ for each $f(i)$ from $1$ to $n$.

  * For $f(1)$, the only possible value of $j$ is $1$.    * For $f(2)$, the only possible value of $j$ is $2$.    * For $f(3)$, the possible values of $j$ are $2$ and $3$.    * For $f(4)$, the possible values of $j$ are $2$ and $3$.    * For $f(5)$, the possible values of $j$ are $2$, $3$, and $4$.

Title: Eliminating Balls With Merging (Hard Version)
time_limit_ms: 4000

Description: Drink water.

— Sun Tzu, The Art of Becoming a Healthy Programmer

This is the hard version of the problem. The only difference is that $x=1$ in this version. You must solve both versions to be able to hack.

You are given two integers $n$ and $x$ ($x=1$). There are $n$ balls lined up in a row, numbered from $1$ to $n$ from left to right. Initially, there is a value $a_i$ written on the $i$-th ball.

For each integer $i$ from $1$ to $n$, we define a function $f(i)$ as follows:

  * Suppose you have a set $S = \\{1, 2, \ldots, i\\}$.

  * In each operation, you have to select an integer $l$ ($1 \leq l < i$) from $S$ such that $l$ is not the largest element of $S$. Suppose $r$ is the smallest element in $S$ which is greater than $l$.

    * If $a_l > a_r$, you set $a_l = a_l + a_r$ and remove $r$ from $S$.      * If $a_l < a_r$, you set $a_r = a_l + a_r$ and remove $l$ from $S$.      * If $a_l = a_r$, you choose either the integer $l$ or $r$ to remove from $S$:        * If you choose to remove $l$ from $S$, you set $a_r = a_l + a_r$ and remove $l$ from $S$.        * If you choose to remove $r$ from $S$, you set $a_l = a_l + a_r$ and remove $r$ from $S$.

  * $f(i)$ denotes the number of integers $j$ ($1 \le j \le i$) such that it is possible to obtain $S = \\{j\\}$ after performing the above operations exactly $i - 1$ times.

For each integer $i$ from $x$ to $n$, you need to find $f(i)$.

Input: The first line contains $t$ ($1 \leq t \leq 10^4$) — the number of test cases.

The first line of each test case contains two integers $n$ and $x$ ($1 \leq n \leq 2 \cdot 10^5; x = 1$) — the number of balls and the smallest index $i$ for which you need to find $f(i)$.

The second line of each test case contains $a_1, a_2, \ldots, a_n$ ($1 \leq a_i \leq 10^9$) — the initial number written on each ball.

It is guaranteed that the sum of $n$ over all test cases does not exceed $2 \cdot 10^5$.

Output: For each test case, output $n-x+1$ space separated integers on a new line, where the $j$-th integer should represent $f(x+j-1)$.

Examples:
input:
3
5 1
1 2 3 2 1
7 1
4 5 1 2 1 4 5
11 1
1 2 3 1 1 9 3 2 4 1 3
output:
1 1 2 2 3
1 1 1 1 1 3 4
1 1 2 2 2 1 1 1 3 3 4

Note: In the first test case, below are the possible values of $j$ for each $f(i)$ from $1$ to $n$.

  * For $f(1)$, the only possible value of $j$ is $1$.    * For $f(2)$, the only possible value of $j$ is $2$.    * For $f(3)$, the possible values of $j$ are $2$ and $3$.    * For $f(4)$, the possible values of $j$ are $2$ and $3$.    * For $f(5)$, the possible values of $j$ are $2$, $3$, and $4$.

Algorithm Problem:
Title: Eliminating Balls With Merging (Hard Version)
time_limit_ms: 4000
memory_limit_mb: 512
Description: Drink water.

— Sun Tzu, The Art of Becoming a Healthy Programmer

This is the hard version of the problem. The only difference is that $x=1$ in this version. You must solve both versions to be able to hack.

You are given two integers $n$ and $x$ ($x=1$). There are $n$ balls lined up in a row, numbered from $1$ to $n$ from left to right. Initially, there is a value $a_i$ written on the $i$-th ball.

For each integer $i$ from $1$ to $n$, we define a function $f(i)$ as follows:

  * Suppose you have a set $S = \\{1, 2, \ldots, i\\}$.

  * In each operation, you have to select an integer $l$ ($1 \leq l < i$) from $S$ such that $l$ is not the largest element of $S$. Suppose $r$ is the smallest element in $S$ which is greater than $l$.

    * If $a_l > a_r$, you set $a_l = a_l + a_r$ and remove $r$ from $S$.      * If $a_l < a_r$, you set $a_r = a_l + a_r$ and remove $l$ from $S$.      * If $a_l = a_r$, you choose either the integer $l$ or $r$ to remove from $S$:        * If you choose to remove $l$ from $S$, you set $a_r = a_l + a_r$ and remove $l$ from $S$.        * If you choose to remove $r$ from $S$, you set $a_l = a_l + a_r$ and remove $r$ from $S$.

  * $f(i)$ denotes the number of integers $j$ ($1 \le j \le i$) such that it is possible to obtain $S = \\{j\\}$ after performing the above operations exactly $i - 1$ times.

For each integer $i$ from $x$ to $n$, you need to find $f(i)$.

Input: The first line contains $t$ ($1 \leq t \leq 10^4$) — the number of test cases.

The first line of each test case contains two integers $n$ and $x$ ($1 \leq n \leq 2 \cdot 10^5; x = 1$) — the number of balls and the smallest index $i$ for which you need to find $f(i)$.

The second line of each test case contains $a_1, a_2, \ldots, a_n$ ($1 \leq a_i \leq 10^9$) — the initial number written on each ball.

It is guaranteed that the sum of $n$ over all test cases does not exceed $2 \cdot 10^5$.

Output: For each test case, output $n-x+1$ space separated integers on a new line, where the $j$-th integer should represent $f(x+j-1)$.

Examples:
input:
3
5 1
1 2 3 2 1
7 1
4 5 1 2 1 4 5
11 1
1 2 3 1 1 9 3 2 4 1 3
output:
1 1 2 2 3
1 1 1 1 1 3 4
1 1 2 2 2 1 1 1 3 3 4

Note: In the first test case, below are the possible values of $j$ for each $f(i)$ from $1$ to $n$.

  * For $f(1)$, the only possible value of $j$ is $1$.    * For $f(2)$, the only possible value of $j$ is $2$.    * For $f(3)$, the possible values of $j$ are $2$ and $3$.    * For $f(4)$, the possible values of $j$ are $2$ and $3$.    * For $f(5)$, the possible values of $j$ are $2$, $3$, and $4$.

**Output format:**

```

Think step by step.

Response:
To expose the bug in the provided code, we need to focus on edge cases and scenarios that might cause the algorithm to fail. Here are the steps to think through the problem:

1. **Understand the Bug**: The provided code seems to have issues with the way it calculates the `prefix` sums and the `next` array. Specifically, the `prefix` array is being calculated incorrectly, and the `next` array might not be properly initialized or used.

2. **Edge Cases**:
   - **Small Input**: Test with a very small input to see if the basic logic is correct.
   - **Equal Values**: Test with an array where all values are the same to see if the merging logic is correct.
   - **Decreasing Sequence**: Test with a decreasing sequence to see if the merging logic handles it correctly.
   - **Increasing Sequence**: Test with an increasing sequence to see if the merging logic handles it correctly.
   - **Mixed Values**: Test with a mixed sequence to see if the merging logic can handle various patterns.

3. **Generate Test Input**:
   - **Small Input**: `1 1 1`
   - **Equal Values**: `3 1 1 1 1`
   - **Decreasing Sequence**: `4 1 4 3 2 1`
   - **Increasing Sequence**: `4 1 1 2 3 4`
   - **Mixed Values**: `5 1 1 3 2 4 2`

Let's choose a mixed values test case to expose potential issues in the merging logic and the `next` array initialization.

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

This test case includes a mix of values that should challenge the merging logic and help identify any issues in the `prefix` and `next` array calculations.

**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.
