hdu2460-Network:边的双连通分量 题目大意:给出一个无向图以及Q次询问,每次询问增加一条无向边,要求输出增加这条边后剩余的桥的数目。 算法:类似于求割点的方法,先做一次dfs求出所有的桥,并且维护这棵dfs树,当一次询问加入一条边(a,b)之后,会在dfs上形成一个环,在这个环上的桥都变为非桥,这个环肯定经过...
思路:先双连通缩点,然后形成一棵树,每次增加一条边,相当于询问这两点路径上有多少条边,这个用树链剖分+线段树处理 代码: #include <cstdio> #include <cstring> #include <algorithm> #include <vector> using namespace std; #pragma comment(linker, "/STACK:1024000000,1024000000"); const int N = 10000...

Network flow is a well-known difficult problem for ACMers. Given a graph, your task is to find out the maximum flow for the weighted directed graph. 对于Acmer来说,网络流是出名的难。给定一个图,找出最大的流。 Input The first line of input contains an integer T, denoting the number of ...
原理如下图所示: 我们可以先将页面需要的静态资源打包并预先加载到客户端的安装包中,当用户安装时,再将资源解压到本地存储中,当 WebView 加载某个 H5 页面时,拦截发出的所有 http 请求,查看请求的资源是否在本地存在,如果存在则直接返回资源。
