众所周知欢乐斗地主这个游戏有一个叫做残局的模式
模式的特征：你和机器人都互相知道对方的牌，且对面的机器人绝顶聪明。
正常的斗地主规则，问你要如何出牌，才能保证你一定能赢。
我们考虑直接爆搜，发现需要搜一年。
于是我们加一个Alpha-Beta剪枝来加速整个爆搜过程即可。
貌似绝大部分情况下都是秒出结果的
目前最长时间只搜了15s（这是v2.0的时间，旧版貌似接近一分钟了）
正确率100%，快速通关利器233333
输入牌型要求：2~9直接输入，JQKA直接输入，10用T表示，大王小王分别用Ww表示。
输入顺子/连对要从小到大输入（按照斗地主规则的从小到大），输入三带一/对，四带二/对，需要先输入三张/四张，再输入剩下的东西
代码貌似只要10k多一点
注意细节
