Problem Statement

Given an n x n 2D matrix, modify a square matrix by rotating it 90 degrees in a clockwise direction.

Note: This rotation should be done in-place, meaning the transformation must occur within the original matrix without using any additional space for another matrix.

Examples

• Example 1:
  • Input: matrix =

[[1,2],
 [3,4]]

• Expected Output:

[[3,1],
 [4,2]]
