Timer is Running

Given a stack, the task is to sort it such that the top of the stack has the greatest element.

Input:
The first line of input will contains an integer T denoting the no of test cases . Then T test cases follow. Each test case contains an integer N denoting the size of the stack. Then in the next line are N space separated values which are pushed to the the stack. 

Output:
For each test case output will be the popped elements from the sorted stack.

Your Task: 
You don't have to read input or print anything. Your task is to complete the function sort() which sorts the elements present in the given stack.

Expected Time Complexity : O(N*N)
Expected Auixilliary Space : O(N) recursive.

Constraints:
1<=T<=100
1<=N<=100

Example(To be used only for expected output):
Input:

2
3
3 2 1
5
11 2 32 3 41

Output:
3 2 1
41 32 11 3 2

Explanation:
For first test case stack will be
1
2
3
After sorting 
3

1

When elements  popped : 3 2 1

Note:The Input/Ouput format and Example given are used for system's internal purpose, and should be used by a user for Expected Output only. As it is a function problem, hence a user should not read any input from stdin/console. The task is to complete the function specified, and not to write the full code.

** For More Input/Output Examples Use 'Expected Output' option **
