对于终于生成的最小生成树中最长边所连接的两点来说 不存在更短的边使得该两点以不论什么方式联通 对于本题来说 最小生成树中的最长边的边长就是使整个图联通的最长边的边长 由此可知仅仅要对给出城市所抽象出的图做一次最小生成树 去树上的最长边就可以 #include<bits/stdc++.h> using namespace std; int T,n,a,dist[1020],m[1020][1020]; void prim() { bool p[1020]; for(int i=2;i<=n…

Highways POJ-1751 最小生成树 Prim算法 题意 有一个N个城市M条路的无向图,给你N个城市的坐标,然后现在该无向图已经有M条边了,问你还需要添加总长为多少的边能使得该无向图连通.输出需要添加边的两端点编号即可. 解题思路 这个可以使用最短路里面的Prim算法来实现,对于已经连接的城市,处理方式是令这两个城市之间的距离等于0即可. prim算法可以实现我们具体的路径输出,Kruskal算法暂时还不大会. 代码实现 #include<cstdio> #include<cs…
