?????????? 自己根据状态转移图的思想，花了两天时间写的程序....写程序，其实，挺好的，挺有意思，个中的感受，偶很难讲明白，一个字“爽”！！其实，这个系统也挺有前途的呵呵！！！
?“讲白了”，写这个程序的目的，其实是因为，“不爽”*,总在我面前摆出一副很自信很牛的样子，看样子让人很不爽~~~亨（在程序员面前挑战技术，表面上看是在挑战技术，其实是在挑战他们的自尊！）、（其实，我觉得我很低调，很多时候都不喜欢表现自己，而且愿意倾听别人的意见，我想说的是“我低调并不代表我不行，我沉默不是我喜欢这样子的，是环境让我变成这样，正如老大说“要深入研究得耐得住寂寞！！””）为了自尊，偶决定亲自操刀~~~你懂的，难道我就不会吗？我贴出来也不给你~~~~亨！
