题目要求
Given a matrix A
, return the transpose of A
.
The transpose of a matrix is the matrix flipped over it‘s main diagonal, switching the row and column indices of the matrix.
题目分析及思路
题目要求得到矩阵的转置矩阵。可先得到一个行数与原矩阵列数相等、列数与原矩阵行数相等的矩阵,再对原矩阵进行遍历。
python代码?
class Solution:
def transpose(self, A: ‘List[List[int]]‘) -> ‘List[List[int]]‘:
rows, cols = len(A), len(A[0])
res = [[0] * rows for _ in range(cols)]
for row in range(rows):
for col in range(cols):
res[col][row] = A[row][col]
return res
