题意: 首先给你一个图,需要你求出最小生成树,首先输入n个节点,用大写字母表示各节点,接着说有几个点和它相连,然后给出节点与节点之间的权值.拿第二个样例举例:比如有3个节点,然后接下来有3-1行表示了边的情况,拿第一行来说:A 2 B 10 C 40表示A有2个邻点,B和C,AB权值是10,AC权值是40. 思路: 直接套prime算法模板和kuskal算法模板,然后处理下数据就可以了. 代码: prime: #include <iostream> #include <cstdio>…
题意: 输入n,然后接下来有n-1行表示边的加边的权值情况.如A 2 B 12 I 25 表示A有两个邻点,B和I,A-B权值是12,A-I权值是25.求连接这棵树的最小权值. 思路: 一开始是在做莫队然后发现没学过最小生成树,就跑过来做模板题了... Kruskal的使用过程:先按权值大小排序,然后用并查集判断是否能加这条边 Kruskal详解博客:[贪心法求解最小生成树之Kruskal算法详细分析]---Greedy Algorithm for MST 考试周还在敲代码...我... upd…

注意: 注意数组越界问题(提交出现runtimeError代表数组越界) 刚开始提交的时候,边集中边的数目和点集中点的数目用的同一个宏定义,但是宏定义是按照点的最大数定义的,所以提交的时候出现了数组越界问题,以后需要注意啦. Description The Head Elder of the tropical island of Lagrishan has a problem. A burst of foreign aid money was spent on extra roads betwe…
