题目: Toeplitz Matrix 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. Example 1: Input: matrix = [[1,2,3,4],[5,1,2,3],[9,5,1,2]]Out…

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. Example 1: Input: matrix = [[1,2,3,4],[5,1,2,3],[9,5,1,2]] Output: True Explanati…

之所以专门定义两个新的概念,在于它们特殊的形式,带来的特别的形式. 1. Toeplitz matrix 对角为常数: n×n 的矩阵 A 是 Toepliz 矩阵当且仅当,对于 Ai,j 有: Ai,j=Ai+1,j+1=ai−j ⎡⎣⎢⎢⎢⎢⎢⎢afghibafghcbafgdcbafedcba⎤⎦⎥⎥⎥⎥⎥⎥ . i−j 表示行号减去列号,对于 n×n 的 Toeplize 矩阵共 2n−1 个不同的值,即 a1−n,a2−n,-,a−1,0,a1,-,an−1. ⎡⎣⎢⎢⎢⎢⎢⎢⎢⎢⎢⎢…

Question 766. Toeplitz Matrix Solution 题目大意: 矩阵从每条左上到右下对角线上的数都相等就返回true否则返回false 思路: 遍历每一行[i,j]与[i+1,j+1]是否相等,不等就返回false,相等就接着遍历,都遍历完了就返回true Java实现: public boolean isToeplitzMatrix(int[][] matrix) { int i = 0; while (i < matrix.length - 1) { int j =…

这是悦乐书的第312次更新,第333篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第181题(顺位题号是766).如果从左上角到右下角的每个对角线具有相同的元素,则矩阵是Toeplitz.现在给定一个M×N矩阵,当且仅当矩阵是Toeplitz时返回True.例如: 输入:矩阵= [[1,2,3,4],[5,1,2,3],[9,5,1,2]] 输出:true 说明:在上面的网格中,对角线是:"[9]","[5,5]","[1,1…

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. Example 1: Input: matrix = [   [1,2,3,4],   [5,1,2,3],   [9,5,1,2] ] Output: True…
