https://codeforces.com/problemset/problem/4/C 用来哈希的一道题目,用map也可以强行过,但是性能慢了6倍,说明是在字符串比较的时候花费了接近6倍的时间. 假如时间性能允许的话不妨用map存hash值,这样就可以让他自然溢出了.基数我喜欢选23333,溢出选择ll自然溢出(反正是map存的可以是负的) 自带hash型map,也是慢到感人. #include<bits/stdc++.h> using namespace std; int n; stri…

[题目链接]:http://codeforces.com/problemset/problem/22/C [题意] 给你n个点; 要求你构造一个含m条边的无向图; 使得任意两点之间都联通; 同时,要求这张图; 在删掉第x个节点之后,会有一些点之间变成不联通的; (两点之间最多连一条边) [题解] 把v和某一个点x连在一起; 然后除了这两个点之外的其他n-2个点; 先每一个点都和v连一条边; 保证联通; 然后如果边数还有剩余; 就在那剩余的n-2个点之间一直连边,直到练成一个团(n-2个点的完全图…

题意 有个人要从\(s\)走到\(t\),经过的路径给定.导航系统每次会显示当前节点到\(t\)的最短路,有多条就显示其中之一.这个人如果按照导航走,那么啥都没变.如果没有按导航走导航就会重新导航.问重新导航的最小和最大次数. 解题思路 建反图,在反图上以\(t\)为源跑dijkstra最短路. 在原图上dfs 若下一个节点到\(t\)的距离是所有邻接节点中最短的 如果到\(t\)最短的节点只有一个,那么什么都不变. 如果不止一个,那么最大次数加1. 若下一个节点到\(t\)的距离不是所有邻接节…
