程序目的：
输入一个任意大小的迷宫，用栈求出一条走出迷宫的路径，并
显示在屏幕上。
程序实现：
可以实现载入迷宫和保存迷宫，附带文件中有4个测试迷宫路径的
文件test1~4.dd。请将这些文件拷贝到TC当前目录下，或者在载
入时写明完全路径。由于屏幕大小的限制，当用户自己输入迷宫
时一定要注意：迷宫大小是有限制的，不小于4*3,不大于30*20。
否则会出现错误信息。输入开始时全是墙，用上下左右键移动，
用Del键删除墙，形成通路，用Enter键添加墙。输入结束时可以
将迷宫保存下来，以dd为扩展名。输入完毕时用F9键来得到结果，
找到路径时，屏幕下方会出现Path found，否则出现Path not found。
程序经Turbo C 2.0编译调试成功。运行时不用添加任何运行库。
不可以在VC上编译。

求走迷宫的算法！（计算机的算法）（编程也可以~
我的思路：
按照人类走迷宫的方法，贴着左边走，左边有路就向左走，左边没路向前走，左边前面都没路向右走
机器人的应该是：1.判断左边是否有墙，无墙：机器人左转，前进一步，继续判断左。。
2.左边有墙，则判断前方是否有墙，无则向前一步，跳回第一步
3.前方有墙（此时状态是左有墙，前有墙），则向机器人右转，跳回第一步
另外有个前提条件，机器人转弯需要原地转，有转弯半径的肯定不行。
还有个问题，就是机器人自己不知道自己已经从迷宫出来了，会一直走。。
状压DP，或者记忆化搜索。
一般的就是F[i,j,k]表示站在i,j点，当前已经得到了k的状态。然后转移。

#钭吴# 以起点为首节点开始分支,分支的个数就是当前节点有几个位置可以走,节点内容为当前所在迷宫位置 就这样不停的分支,每生成一个节点就判断是否为终点位置,是则得出结果, 输出路径.因为生成的树的层数对应的正是已走的步数,所以第一个结果必是最短的 另外在数据结构上可以多设计一个数组记录已经走过的位置,当生成的节点位置已经被走过,则可删除该节点, 这样可以减少搜索次数. 这是类似的广度搜索,如果数据量不多,用递归会更直观,简单.
