leetcode - 48.Rotate Image

python式解法

利用zip函数和*,首先将matrix反向，再利用zip压缩即可,*表示选择列表中的子列表，*list

class Solution:
    def rotate(self, matrix):
        """
        Do not return anything, modify matrix in-place instead.
        """
        matrix[::] = zip(*matrix[::-1])

索引法

class Solution:
    def rotate(self, matrix: List[List[int]]) -> None:
        """
        Do not return anything, modify matrix in-place instead.
        """
        n = len(matrix[0])
        matrix[::] = [[matrix[n-j-1][i] for j in range(n)] for i in range(n)]
