HDU 6203 ping ping ping [LCA,贪心,DFS序,BIT(树状数组)]

题目链接:[http://acm.hdu.edu.cn/showproblem.php?pid=6203] 题意 :给出一棵树,如果(a,b)路径上有坏点,那么(a,b)之间不联通,给出一些不联通的点对,然后判断最少有多少个坏点. 题解 :求每个点对的LCA,然后根据LCA的深度排序.从LCA最深的点对开始,如果a或者b点已经有点被标记了,那么continue,否者标记(a,b)LCA的子树每个顶点加1. #include<Bits/stdc++.h> using namespace std;

HDU 5542 The Battle of Chibi dp+树状数组

题目:http://acm.hdu.edu.cn/showproblem.php?pid=5542 题意:给你n个数,求其中上升子序列长度为m的个数 可以考虑用dp[i][j]表示以a[i]结尾的长度为j的上升子序列有多少 裸的dp是o(n2m) 所以需要优化 我们可以发现dp的第3维是找比它小的数,那么就可以用树状数组来找 这样就可以降低复杂度 #include<iostream> #include<cstdio> #include<cstring> #include

[hdu 2102]bfs+注意INF

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=2102 感觉这个题非常水,结果一直WA,最后发现居然是0x3f3f3f3f不够大导致的--把INF改成INF+INF就过了. #include<bits/stdc++.h> using namespace std; bool vis[2][15][15]; char s[2][15][15]; const int INF=0x3f3f3f3f; const int fx[]={0,0,1,-1};

HDU 3555 Bomb (数位DP)

数位dp,主要用来解决统计满足某类特殊关系或有某些特点的区间内的数的个数,它是按位来进行计数统计的,可以保存子状态,速度较快.数位dp做多了后,套路基本上都差不多,关键把要保存的状态给抽象出来,保存下来. 简介: 顾名思义,所谓的数位DP就是按照数字的个,十,百,千--位数进行的DP.数位DP的题目有着非常明显的性质: 询问[l,r]的区间内,有多少的数字满足某个性质 做法根据前缀和的思想,求出[0,l-1]和[0,r]中满足性质的数的个数,然后相减即可. 算法核心: 关于数位DP,貌似写法还是
