题意: 给出一个N个节点的有向图.图中任意两点进行通信的代价为路径上的边权和.如果两个点能互相到达那么代价为0.问从点0开始向其余所有点通信的最小代价和.保证能向所有点通信. 题解: 求出所有的强连通分量,然后进行缩点操作.最后贪心的找出每个点的最小代价,然后求和. #include <iostream> #include <cstdio> #include <vector> #include <cstring> #include <algorithm…

思路:建一个有向图,指向能引爆对象,把强连通分量缩成一点,只要点燃图中入度为0的点即可.因为入度为0没人能引爆,不为0可以由别人引爆. 思路很简单,但是早上写的一直错,改了半天了,推倒重来才过了... #include<cstdio> #include<set> #include<stack> #include<cstring> #include<algorithm> #define ll long long using namespace st…

题意,从0点出发,遍历所有点,遍历边时候要付出代价,在一个SCC中的边不要付费.求最小费用. 有向图缩点(无需建立新图,,n<=50000,建则超时),遍历边,若不在一个SCC中,用一个数组更新记录最小到达该连通分量的最小边权即可...边聊天,边1A,哈哈... #include<iostream> #include<stack> #include<queue> #include<cstdio> #include<cstring> usin…
