和迷宫问题区别不大,相比于POJ1321的棋盘问题,这里的BFS是三维的,即从4个方向变为6个方向. 用上队列的进出操作较为轻松. #include<iostream> #include<cstdio> #include<cstring> #include<queue> #include<algorithm> using namespace std; char map[35][35][35]; int vis[35][35][35]; int t…

POJ.2251 Dungeon Master (三维BFS) 题意分析 你被困在一个3D地牢中且继续寻找最短路径逃生.地牢由立方体单位构成,立方体中不定会充满岩石.向上下前后左右移动一个单位需要一分钟.你不能对角线移动并且迷宫四周坚石环绕. 若能逃离,则输出逃离需要的最短时间,否则输出Trapped!. 与二维BFS的差别在于,多了一个上下两层.所以除了先后左右移动,还要有上下移动,对于每个位置,总共有6种移动方式,将6种移动方式种可行的每次塞进队列里面就好了. 依旧还要记录歩数.此题没什么大…
