题意：
You are given an n x n 2D matrix representing an image.
Rotate the image by 90 degrees (clockwise).
Follow up:
Could you do this in-place?
解题思路：先将矩阵转置，然后将矩阵的每一行翻转，就可以得到所要求的矩阵了。
代码：
class Solution: # @param matrix, a list of lists of integers # @return a list of lists of integers def rotate(self, matrix): n = len(matrix) for i in range(n): for j in range(i+1, n): matrix[i][j], matrix[j][i] = matrix[j][i], matrix[i][j] for i in range(n): matrix[i].reverse() return matrix
