J - Borg Maze 思路:bfs+最小生成树. #include<queue> #include<cstdio> #include<cstring> #include<iostream> #include<algorithm> #define MAXN 110 using namespace std; int fa[MAXN]; struct nond{ int x,y,z; }v[MAXN*MAXN]; struct none{ int…
在一个迷宫里面需要把一些字母.也就是 ‘A’ 和 ‘B’连接起来,求出来最短的连接方式需要多长,也就是最小生成树,地图需要预处理一下,用BFS先求出来两点间的最短距离, ********************************************************************************** #include<algorithm> #include<stdio.h> #include<; ][] = { {,},{,},{-,},{,…

题目链接: https://vjudge.net/contest/66965#problem/J 具体思路: 首先将每个点之间的最短距离求出(bfs),A 或者 S作为起点跑bfs,这样最短距离就求出来了.然后再用最短路的算法求出最小生成树的权值的和就可以了,getchar的注意事项在代码中解释. #include<iostream> #include<string> #include<cstring> #include<cmath> #include<…

Borg Maze 题意: 题目我一开始一直读不懂.有一个会分身的人,要在一个地图中踩到所有的A,这个人可以在出发地或者A点任意分身,问最少要走几步,这个人可以踩遍地图中所有的A点. 思路: 感觉就算读懂了题目,也比较难想到这用到了最小生成树的知识,因为可以分身,所以每个点可以向其他点都连上边.可以用bfs预处理出所有的S点,A点的连线,再跑一遍最小生成树,即可得出答案.这里有几点注意,一开始我bfs没有记录step,而是直接找到一点后算曼哈顿距离,这是不对的,因为可能是绕了一个圈到了这个点.还…
