解题报告:这题看着别人板子写的,竟然是线段树,真没看出来Orz,思路就是我们通过m次操作,建立线段树,并且每次给区间l,r 或上一个d值,最后检查每次询问的范围内想与的值还是不是原来的值,如果不是就输出no#include<iostream>#include<cstring>#include<vector>#include<algorithm>#include<map>#include<set>#include<.

牛客多校: https://ac.nowcoder.com/acm/contest/5673/I 题意:每次从两个数中选一个,也可以不选,但是选不能选之前重复的。做法:同一行连一个边,然后一个图中有环的贡献就是这个图的大小;没环就是大小-1,用并查集维护就可以 #include <bits/stdc

Undoubtedly you know of the Fibonacci numbers. Starting with F1 = 1 and F2 = 1, every next number is the sum of the two previous ones. This results in

题意:给你一个有趣图的定义:在这个图中有一个根,根与每个点都有边和回边,除了根之外,其他的点的出度和入度都为2,然后给你一个图让你经过几步操作可以使此图变为有趣图,操作为:删边或者加边。思路:枚举根,然后删除与根有关的边,重新建图,用二分图求最大匹配,可以用匈牙利算法,加的边数:满足题中有关根的加边...

这个题目是一个求最大权完美匹配的题目,我们需要注意两点:一、要处理好负边的情况。二、要注意N和M不一定相等。
对于第一点的处理,我见过的有两种处理方式:①将所有边都初始化成负边,这样当做N-M之间所有的边都是存在的去进行匹配,如果最后发现边权为正的匹配数为N的话就是有解的,否则无解。②将为负值的边视为不存在,并且在KM算法过程中,如果发现当前状态不能再进行增广,则无解。
对于第二
