We have a two dimensional matrix A where each value is 0 or 1. A move consists of choosing any row or column, and toggling each value in that row or column: changing all 0s to 1s, and all 1s to 0s. After making any number of moves, every row of this…

这是悦乐书的第324次更新,第347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194题(顺位题号是832).给定二进制矩阵A,我们想要水平翻转图像,然后反转它,并返回结果图像. 水平翻转图像意味着图像的每一行都是相反的. 例如,水平翻转[1,1,0]会产生[0,1,1]. 反转图像意味着每个0替换为1,每个1替换为0.例如,反转[0,1,1]会产生[1,0,0]. 例如: 输入:[[1,1,0],[1,0,1],[0,0,0]] 输出:[[1,0,0],[0,…

822. 翻转卡片游戏 在桌子上有 N 张卡片,每张卡片的正面和背面都写着一个正数(正面与背面上的数有可能不一样). 我们可以先翻转任意张卡片,然后选择其中一张卡片. 如果选中的那张卡片背面的数字 X 与任意一张卡片的正面的数字都不同,那么这个数字是我们想要的数字. 哪个数是这些想要的数字中最小的数(找到这些数中的最小值)呢?如果没有一个数字符合要求的,输出 0. 其中, fronts[i] 和 backs[i] 分别代表第 i 张卡片的正面和背面的数字. 如果我们通过翻转卡片来交换正面与背面上…
