迷宫问题是取自心理学的一个古典实验。实验中，把一只老鼠从一个没有顶的大盒子的门放入，在盒中设置了许多墙，对行进的方向形成了多处阻挡。盒子仅仅有一个出口，在出口处放置了一块奶酪，吸引老鼠在迷宫中寻找道路以到达出口。重复对老鼠进行上述实验，看老鼠能在多久找到出口。

本算法实现迷宫问题求解。-The maze problem is a classical experiment taken　psychology. In the experiment, a mouse was put into the door of a large box with no top, and a plurality of walls were arranged in the box to block the direction of travel. The box has only one exit, and a piece of cheese is placed at the exit, attracting rats to find a road in the labyrinth to reach the exit. Repeat the experiment with mice to see how long rats can find the exit.

The algorithm to solve the maze problem.
