题目描述
你准备开发一个导航软件。使用者在一个 m×n 格的迷宫(表示有 m 行、n 列),其中有可走的也有不可走的,如果用 1 表示可以走,0 表示不可以走,文件读入这 m×n 个数据和起始点、结束点。现在要你编程找出所有可行的道路,要求所走的路中没有重复的点,走时只能是上下左右四个方向。如果一条路都不可行,则输出相应信息(用 -1 表示无路)。
in
第一行是两个数 m,n(1<m,n<15),接下来是 m 行 n 列由 1 和 0 组成的数据,最后两行是起始点和结束点。
out
所有可行的路径,描述一个点时用 (x,y) 的形式,除开始点外,其他的都要用 ->
表示方向。
如果没有一条可行的路则输出-1。
