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<; ][] = { {,},{,},{-,},{,…

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…
