【LeetCode】54. 螺旋矩阵 python实现

解题思路

拿一行，逆时针转一下

python 代码

class Solution:
    def spiralOrder(self, matrix: List[List[int]]) -> List[int]:
        
        res = []
        while matrix:
            res += matrix.pop(0)
            matrix = list(zip(*matrix))
            matrix = matrix[::-1]
        return res

s = Solution()
result = s.spiralOrder([[1,2,3],[4,5,6],[7,8,9]])
print(result)
