题目链接 http://poj.org/problem?id=1573 题意 一个机器人在给定的迷宫中行走,在迷宫中的特定位置只能按照特定的方向行走,有两种情况:①机器人按照方向序列走出迷宫,这时输出机器人走出迷宫的步数:②机器人在迷宫中陷入了循环,这种情况要输出机器人陷入循环前所走的步数以及循环的步数. 思路 走迷宫问题一般使用BFS或DFS求解,这里我使用DFS来求解.机器人能顺利走出迷宫的情况比较容易判断,主要是如何判断机器人陷入了循环以及陷入循环后的输出.我使用visit[r][c]来记…

迷宫问题 Description 定义一个二维数组: int maze[5][5] = { 0, 1, 0, 0, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 1, 0, }; 它表示一个迷宫,其中的1表示墙壁,0表示可以走的路,只能横着走或竖着走,不能斜着走,要求编程序找出从左上角到右下角的最短路线. Input 一个5 × 5的二维数组,表示一个迷宫.数据保证有唯一解. Output 左上角到右下角的最短路径,格式如样例所…
