这是一道2016湘潭邀请赛的题目,记得那个时候看到这个题目就想到了最短生成树,然后给别人做,WA了,最后发现是有向图,然后我自己去写了个搜索,结果是RE吧 今天刚刚好想到这个题目,然后再来做,发现这个真的是个水题,但是当初看题目都没看懂,我也是醉了,题目都已经要求了是从第一个到最后一个的最短的路径,我们想岔了,然后鸭蛋... http://202.197.224.59/OnlineJudge2/index.php/Problem/read/id/1245 #include <stdio.h>…

http://lightoj.com/volume_showproblem.php?problem=1245 题目大意:一个数n除以1到n之和 分析:暴力肯定不行,我们可以先求1~sqrt(n)之间的每个数的个数,然后再求n除以1~sqrt(n)之间的数的和 这样算下来就只有2*sqrt(n)的复杂度 最后还要排除多加的,. #include<stdio.h> #include<string.h> #include<stdlib.h> #include<algor…

题目链接 题意:求给定的字符串的最长回文子串 分析:做法是构造一个新的字符串是原字符串+反转后的原字符串(这样方便求两边回文的后缀的最长前缀),即newS = S + '$' + revS,枚举回文串中心位置,RMQ询问LCP = min (height[rank[l]+1] to height[rank[r]]),注意的是RMQ传入参数最好是后缀的位置,因为它们在树上的顺序未知,且左边还要+1. #include <cstdio> #include <algorithm> #in…
