题目地址 https://leetcode.com/problems/set-matrix-zeroes/ 题目描述 Given a m x n matrix, if an element is 0, set its entire row and column to 0. Do it in-place. Example 1: Input: [ [1,1,1], [1,0,1], [1,1,1] ] Output: [ [1,0,1], [0,0,0], [1,0,1] ] Example 2: Input: [ [0,1,2,0], [3,4,5,2], [1,3,1,5] ] Output: [ [0,0,0,0], [0,4,5,0], [0,3,1,0] ] Follow up: A straight forward solution using O(m**n) space is probably a bad idea. A simple improvement uses O(m + n) space, but still not the best solution. Coul....
