题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=3018 题目大意:有n个点,m条边,人们希望走完所有的路,且每条道路只能走一遍.至少要将人们分成几组. 解题思路:先用并查集求出所有的连通块,然后判断每个连通块内点的度数,如果有奇数点则需要的组数ans+=奇数点/2:反之,所需组数ans+=1.注意:如果遇到孤立点即度数为0的点则不用算进去,因为没有跟他相连的边. 代码: #include<iostream> #include<cstdio&…

1530:Ant Trip [题目描述] 原题来自:2009 Multi-University Training Contest 12 - Host by FZU 给你无向图的 N 个点和 M 条边,保证这 M 条边都不同且不会存在同一点的自环边,现在问你至少要几笔才能所有边都画一遍.(一笔画的时候笔不离开纸) [输入] 多组数据,每组数据用空行隔开. 对于每组数据,第一行两个整数 N,M 表示点数和边数.接下去 M 行每行两个整数 a,b,表示 a,b 之间有一条边. [输出] 对于每组数据,…
