Problem Statement

You are given a square matrix of dimensions ‘N * N’. You have to rotate the matrix 90 degrees in a clockwise direction.

EXAMPLE:

Input: 'N' = 2, 'NUMS' = [[1, 2], [3, 4]]

Output: [[3, 1], [4, 2]]

Here the given matrix is rotated 90 degrees in a clockwise direction.

Detailed explanation ( Input/output format, Notes, Constraints, Images )

Input Format :

The first line of the input contains an integer, 'T’, denoting the number of test cases.

The first line of each test case will contain a single integer ‘N’, denoting the dimension of the matrix.

Each of the next ‘N’ lines contains ‘N’ integers separated by single spaces denoting the elements of the square matrix ‘NUMS’.

Output format :

For each test case, print the matrix after rotating 90 degrees in a clockwise direction.

Note :

You don't need to print anything. It has already been taken care of. Just implement the given function.

Constraints :

1 <= 'T' <= 10
2 <= 'N' <= 10^2
1 <= 'NUMS[i]' <= 10^5

Time Limit: 1 sec

Explanation Of Sample Input 1 :

For the first test case,
'N' = 2, 'NUMS' = [ [1, 2], [3, 4]]
After rotation 90 degrees in a clockwise direction the matrix will be:
‘NUMS’ = [ [3, 1], [4, 2] ].

For the second test case,
'N' = 3, 'NUMS' = [ [1, 2, 3], [4, 5, 6], [7, 8, 9] ]
After rotation 90 degrees in a clockwise direction the matrix will be:
‘NUMS’ = [ [7, 4, 1], [8, 5, 2], [9, 6, 3] ].
