1861

题意：

又M个点 N条边求构成最小生成树的最大边和所有边的两个端点

裸最小生成树加上了两个优化

1.路径压缩：查找x元素的根节点d时,将x的所有父亲节点全部直接变成根节点的子节点

以减少下次查找的查找时间

2.在并查集并的过程中考虑两个节点谁的子节点多，少的作为子节点

ZOJ 1586 QS Network prim优化模板

链接: 1586 题意: 有一个N X N的网络,每两个点都有边相连,边的权值用邻接矩阵输入,每个点也有一个权值,当它们之间的那条边被选取时,需要加上两个点的权值.求这个网络的最小生成树. 直接套用prim算法的模板其中用到一个节约内存的优化将lowdistance 和visit 两个数组结合起来如果访问过lowdistance改成-1即可另外该题中边的权值应为边本身的权值加上两端点的权值. #include<iostream> #include<cstdio> #inc

POJ 1861 Network(隐含最小生成树打印方案)

题意求n个点m条边的图的连通子图中最长边的最小值实际上就是求最小生成树中的最长边因为最小生成树的最长边肯定是所有生成树中最长边最小的那么就也变成了最小生成树了不要被样例坑到了样例并不是最佳方案只是最长边与最小生成树的最长边相等题目是特判直接用最小生成树做就行 #include<cstdio> #include<cstring> #include<algorithm> using namespace std; const int N =
