1034 Head of a Gang (30 分)
One way that the police finds the head of a gang is to check people’s phone calls. If there is a phone call between A and B, we say that A and B is related. The weight of a relation is defined to be the total time length of all the phone calls made betw强化阶段 Day 22 算法笔记 10.3 图的遍历

题目描述： 该题的目的是要你统计图的连通分支数。 输入： 每个输入文件包含若干行，每行两个整数i,j，表示节点i和j之间存在一条边。 输出： 输出每个图的联通分支数。 样例输入： 1 4 4 3 5 5 样例输出： 2 实现代码： #include<cstdio> #include<algorithm> #include<vector> using namePAT A1034 Head of a Gang
通话记录有1000条，人数可能为2000给的人名是string，用两个map记录数字转换每遍历过一条边后就把这条边的权值设为0，防止出现回路遍历死循环 #include <cstdio> #include <vector> #include <iostream> #include <queue> #include <algorithm> #include <map> using namespace s图的dfs+string的输入只能用cin
