城堡游戏

城堡游戏

游戏描述：

1.这个程序的任务是通过玩家的输入的方向（纯文字）在虚构的城堡内移动（以纯文字作为移动后的返回结果）。

2.这个程序接受help、bye、go south、go north、go west、go east六种命令，要求命令单独一行输入并在结束时敲回车，另外如果接受go xxx的不合规信息会输出不存在这样的房间。

3.help提供帮助信息，bye结束游戏，go后面空一格加south、north、west、east表示在虚构的城堡中移动。

4.有四个房子，分别是：大堂，小酒吧，书房，卧室。

城堡东面是大堂西面是小酒吧南面是书房。

书房的东面是卧室。

卧室与大堂不相连。

卧室的上面是次卧。
