Rotate Matrix by 90 degrees clockwise | Rotate Image

This video explains the best way to rotate a matrix or rotate an image by 90 degrees. I have explained the most optimal inplace algorithm which takes constant extra space O(1) and linear time complexity of size of the matrix O(MN). I have also discussed the possible follow-up problems.

We need to use extra matrix for this technique. Otherwise it is impossible to transpose and then reverse.
