迷宫问题。以一个 m*n的长方阵表示迷宫，0和1分别表示迷宫中的通路和障碍。设计一个程序，对任意设定的迷宫，求出一条从入口到出口的通路，或得出没有通路的结论

起点就是方阵中的（1，1）终点就是（m-1，n-1） -Maze. With an m* n matrix, said the long labyrinth of 0 and 1, respectively, the maze of paths and obstacles. Designing a program, for any set of the maze, find a path from the entrance to the export, or come to the conclusion there is no access point is a square matrix of the (1,1) The end is (m-1, n-1)
