Given a m x n matrix, if an element is 0, set its entire row and column to 0. Do it in place. 解决思路 难点在于如何不使用辅助空间。 一个巧妙的想法是, 1. 使用两个标记变量,row0_has_zeros和col0_has_zeros分别表示矩阵中的第一行和第一列中是否包含0元素; 2. 从矩阵的内层元素开始遍历...
Given an m x n integer matrix matrix, if an element is 0, set its entire row and column to 0's. You must do it in place. Example 1: Input: matrix = [[1,1,1],[1,0,1],[1,1,1]] Output: [[1,0,1],[0,0,0],[1,0,1]] Example 2: Input: matrix = [[0,1,2,0...
