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.
``````
##### 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

##### Sample Output 1 :
``````3 1
4 2
7 4 1
8 5 2
9 6 3
``````
##### 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] ].
