Caocao's Bridges 题意:曹操赤壁之战后卷土重来,他在n个小岛之间建立了m座桥.现在周瑜只有一颗炮弹,他只能炸毁一座桥使得这些岛屿不再连通.每座桥上都可能会有士兵把手,如果想安放***那么派出的士兵就不得少于桥上的士兵.求周瑜最少需要多少士兵. 思路:首先三大坑点:图原来就不连通所以不用炸毁任何一座桥.两个小岛之间有重边,那么不管炸毁哪座都无影响,也就是说重边不是桥.如果桥上本来就没有士兵是不是不用派出呢, 当然不是,还要一个放***的啊..... int ti,top,ans,q…

题目链接: Hdu 4738 Caocao's Bridges 题目描述: 有n个岛屿,m个桥,问是否可以去掉一个花费最小的桥,使得岛屿边的不连通? 解题思路: 去掉一个边使得岛屿不连通,那么去掉的这个边一定是一个桥,所以我们只需要求出来所有的桥,然后比较每个桥的花费,选取最小的那个就好. 看起来很简单的样子哦!但是这个题目有很多的细节: A:题目中有重边,以后写Tarjan还是清一色判断重边吧.(除非题目特别要求) B:m个桥有可能连通不了这n个桥,这个时候不需要花费. C:当最小花费桥的花费…
