题意:给定n个节点m条边的有向带权图,求以0为根节点的最小树形图权值大小 用这个代码的时候要注意,这里的数据是从0开始的,边也是从0开始算, 所以在打主代码的时候,如果是从1开始,那么算法里面的从0开始的位置也要相应修改. 特别是下面的  node_circle; #include<cstdio> #include<algorithm> #include<string.h> using namespace std; ; ; const int inf=0x3f3f3f3…

第一个部分 前4题 次小生成树 算法:首先如果生成了最小生成树,那么这些树上的所有的边都进行标记.标记为树边. 接下来进行枚举,枚举任意一条不在MST上的边,如果加入这条边,那么肯定会在这棵树上形成一个环,如果还要维护处树的特点 那么就要在这个环上删去一条边,这样他还是树,删掉的边显然是这条链上权值最大边更可能形成次小生成树.那么就有2中方法可以做. 第一种PRIM在prim时候直接可以做出这个从I到J的链上权值最大的值MAX[i][j]; 同时可以用kruskal同样方式标记树边,然后DFS跑…
