Given a square matrix[][] of size N x N. The task is to rotate it by 90 degrees in an anti-clockwise direction without using any extra space.
Example 1:
Input:
N = 3
matrix[][] = [[1 2 3],
[4 5 6],
[7 8 9]]
Output:
3 6 9
2 5 8
1 4 7
Your Task:
You only need to implement the given function rotate(). Do not read input, instead use the arguments given in the function.
Expected Time Complexity: O(N*N)
Expected Auxiliary Space: O(1)
