由0和1构成的n维方阵M表示一个迷宫，其中0表示通路，1表示墙壁。迷宫入口为(1,1),出口为(n,n)。迷宫随机产生。试编一算法求出从入口点到出口点可沿八个方向前进的一条通路。　　-From 0 and 1 consisting of n-dimensional matrix M express a maze, where 0 indicated that access, said one wall. Maze entrance (1,1), export (n, n). Randomly generated maze. Test series 1 algorithm derived from the entrance point to the export of eight points along the direction of a path.
