题目传送门 题意:给出n个长度为7的字符串,一个字符串到另一个的距离为不同的字符数,问所有连通的最小代价是多少 分析:Kuskal/Prim: 先用并查集做,简单好写,然而效率并不高,稠密图应该用Prim而且要用邻接矩阵,邻接表的效率也不高.裸题但题目有点坑爹:( Kruskal: #include <cstdio> #include <cstring> #include <string> #include <algorithm> #include <…

题目链接:http://poj.org/problem?id=1789 题目意思:给出 N 行,每行7个字符你,统计所有的 行 与 行 之间的差值(就是相同位置下字母不相同),一个位置不相同就为1,依次累加.问最终的差值最少是多少. 额.....题意我是没看懂啦= =......看懂之后,就转化为最小生成树来做了.这是一个完全图,即每条边与除它之外的所有边都连通.边与边的权值是通过这个差值来算出来的. #include <iostream> #include <cstdio> us…

主题链接:http://poj.org/problem?id=1789 思维:一个一个点,每两行之间不懂得字符个数就看做是权值.然后用kruskal算法计算出最小生成树 我写了两个代码一个是用优先队列写的.可是超时啦,不知道为什么.希望有人能够解答.后面用的数组sort排序然后才AC. code: 数组sort排序AC代码: #include<cstdio> #include<queue> #include<algorithm> #include<iostream…

本题链接:点击打开链接 题目大意: 输入n表示卡车辆数,输入每辆卡车编号.即长度为7的字符串,每辆卡车编号均可由其他类型编号衍生过来,求由当中一辆衍生出其他全部的最小衍生次数(有一个字符不同就需衍生一次). 解题思路: 本题能够看做求最小生成树的问题,关键是图的构建.把每两辆车衍生次数作为权值,然后使用prime算法求解最小生成树,详细请參见代码: #include<stdio.h> #include<string.h> #define INF 0xffffff int map[2…
