You are given a board of size n × n, where n is odd (not divisible by 2). Initially, each cell of the board contains one figure.

In one move, you can select exactly one figure presented in some cell and move it to one of the cells sharing a side or a corner with the current cell, i.e. from the cell (i, j) you can move the figure to cells: 

  * (i - 1, j - 1); 
  * (i - 1, j); 
  * (i - 1, j + 1); 
  * (i, j - 1); 
  * (i, j + 1); 
  * (i + 1, j - 1); 
  * (i + 1, j); 
  * (i + 1, j + 1); 



Of course, you can not move figures to cells out of the board. It is allowed that after a move there will be several figures in one cell.

Your task is to find the minimum number of moves needed to get all the figures into one cell (i.e. n^2-1 cells should contain 0 figures and one cell should contain n^2 figures).

You have to answer t independent test cases.

Input

The first line of the input contains one integer t (1 ≤ t ≤ 200) — the number of test cases. Then t test cases follow.

The only line of the test case contains one integer n (1 ≤ n < 5 ⋅ 10^5) — the size of the board. It is guaranteed that n is odd (not divisible by 2).

It is guaranteed that the sum of n over all test cases does not exceed 5 ⋅ 10^5 (∑ n ≤ 5 ⋅ 10^5).

Output

For each test case print the answer — the minimum number of moves needed to get all the figures into one cell.
