Problem of the day
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.
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’.
For each test case, print the matrix after rotating 90 degrees in a clockwise direction.
You don't need to print anything. It has already been taken care of. Just implement the given function.
1 <= 'T' <= 10
2 <= 'N' <= 10^2
1 <= 'NUMS[i]' <= 10^5

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] ].
