DESCRIPTION:给你一个三维的迷宫.问你是否能从起点走到终点.如果能,输出最小步数.对我来说难得就是我没有想到怎么把他给你的三维图转换成map.恩..好像解题报告上说.只要是这种的最短路都要用bfs.用dfs回很难.不太懂耶.>_<... 然后就是普通的bfs了.然后忘了三个输入全为0的时候结束程序.然后WA了一会..然后就没有然后了.233333333333 附代码: #include<stdio.h>#include<string.h>#include<…

POJ 2251 题目大意: 给出一三维空间的地牢,要求求出由字符'S'到字符'E'的最短路径,移动方向可以是上,下,左,右,前,后,六个方向,每移动一次就耗费一分钟,要求输出最快的走出时间.不同L层的地图,相同RC坐标处是相连通的.(.可走,#为墙) 解题思路:从起点开始分别往6个方向进行BFS(即入队),并记录步数,直至队为空.若一直找不到,则困住. /* POJ 2251 Dungeon Master --- 三维BFS(用BFS求最短路) */ #include <cstdio> #i…

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…
