D - Complete Tripartite 思路:这个题是个染色问题.理解题意就差不多写出来一半了.开始的时候还想用离散化来储存每个点的状态,即它连接的点有哪些,但很无奈,点太多了,long long范围内肯定存不完,于是想到用python来写,但是 py 也没有很熟练.....便放弃了. 需要注意的: 要统计总共有多少颜色,不然会漏掉只有两种颜色的情况,这种情况是输出-1的.还有前向星存边的时候记得开两倍. 代码: // Created by CAD on 2019/10/2. #incl…
思路: 任选一点a,和a没有边直接相连的点一定和a在同一个集合,由此构造得到一个集合A.用类似的方法再构造一个集合B,并将剩下的点放在集合C中,就得到了三个集合A,B,C.再检查A,B,C是否符合要求即可. 实现: #include <bits/stdc++.h> using namespace std; ; vector<int> G[N]; int res[N]; int main() { int n, m; while (cin >> n >> m)…

2012年,在伦敦举行的语言大赛中,圭亚那选手Samsunder Balgobin 在回答比赛中最后一道问题 "你如何用一种容易让人理解的方式解释 complete与finished 的区別"时, 给出了他的答案: When you marry the right woman, you are COMPLETE. (娶对老婆,你这一生就完整了.) When you marry the wrong woman, you are FINISHED. (娶错老婆,你这一生就完蛋了.…
在使用vmware的过程中发现创建快照.恢复快照.管理快照等功能突然都变成灰色的,用不了.更觉得夸张的是仅仅剩下关闭虚机按钮是红色的.心想估计是虚机快照没处理完之类的问题导致的,于是想想关闭虚机重启得了. 点击关闭之后提示"xxx is still busy. Please wait until the operation is complete before closing"(其中xxx是你虚机的名字). 记得N早以前遇到过,不过没有记录所以忘记怎么处理的,晕了吧,后悔偷懒没记录…
