POJ1222-EXTENDED LIGHTS OUT POJ3279-Fliptile POJ1753-Flip Game 为什么将着三个题放一起讲呢?因为只要搞明白了其中一点,就可以一次3ac了-- 首先讲下每个题目的意思 1.EXTENDED LIGHTS OUT 给你5行6列的01矩阵,0代表该点的灯是关闭的,1代表该点的灯是开着的,要求出每一栈灯是否按下,使得所有的灯都熄灭,当然,按下某一盏灯时,它附近的灯也会变成原来相反的状态,如图所示. 2.Fliptile 一群奶牛,喜欢白色瓷砖…
-->Fliptile 直接中文翻译:Descriptions: 给你一个01矩阵,矩阵大小为M x N.(1 <= M , N <= 15)每次操作选择一个格子,使得该格子与上下左右四个格子的值翻转.至少多少次操作可以使得矩阵中所有的值变为0?请输出翻转方案,若没有方案,输出"IMPOSSIBLE” .若有多种方案符合题意,请首先输出翻转次数最少的方案:若方案个数仍不唯一,则输出字典序最小的方案. Input 第一行输入两个数:M和N.(1 <= M , N <=…
Description Input 第一行包含一个正整数testcase,表示当前测试数据的测试点编号.保证1≤testcase≤20. 第二行包含三个整数N,M,T,分别表示节点数.初始边数.操作数.第三行包含N个非负整数表示 N个节点上的权值. 接下来 M行,每行包含两个整数x和 y,表示初始的时候,点x和点y 之间有一条无向边, 接下来 T行,每行描述一个操作,格式为“Q x y k”或者“L x y ”,其含义见题目描述部分. Output 对于每一个第一类操作,输出一个非负整数表示答…
