题目描述 给定一个矩阵 A, 返回 A 的转置矩阵. 矩阵的转置是指将矩阵的主对角线翻转,交换矩阵的行索引与列索引. 示例 1: 输入:[[1,2,3],[4,5,6],[7,8,9]] 输出:[[1,4,7],[2,5,8],[3,6,9]] 示例 2: 输入:[[1,2,3],[4,5,6]] 输出:[[1,4],[2,5],[3,6]] 提示: 1 <= A.length <= 1000 1 <= A[0].length <= 1000 思路 新建一个矩阵res,res[i]…

题目要求 A matrix is Toeplitz if every diagonal from top-left to bottom-right has the same element. Now given an M x N matrix, return True if and only if the matrix is Toeplitz. 题目分析及思路 给定一个M x N的矩阵,判断这个矩阵是不是Toeplitz.符合条件的矩阵应满足从左上到右下的每条对角线上的元素都相同.我们可以发现同…
