设想，将25个房间除了起始点(3,3)其余的按照随机顺序生成。则最后输出应该为注释中的各房间数量的5×5的方阵

实际输出

输出一、 gold magic magic plain prop magic magic plain plain stone stone stone start prop stone magic magic prop plain

输出二、 stone stone magic magic magic gold exit prop stone plain plain magic start plain magic plain plain stone prop

输出三、 prop gold stone plain magic plain magic exit plain stone stone prop start magic magic stone magic magic plain

可见都比设想的结果少六个（一行零一列） 求调
