# Rotate a square matrix by 90 degrees counter-clockwise about its center. # TODO Use a matrix instead of a two-dimensional list. for col in xrange(n/2): for row in xrange(col, n - col - 1): temp1 = m ...

You are given an n x n 2D matrix representing an image, rotate the image by 90 degrees (clockwise). You have to rotate the image in-place, which means you have to modify the input 2D matrix directly.
