诈金花是很多男人最爱的卡牌游戏 , 每当你拿到三张牌的时候, 生活重新充满了期待和鸟语花香. 那么我们如果判断手中的牌在所有可能出现的牌中占据的百分比位置呢.
这是最终效果:
这是更多的结果:
在此做些简单的说明:
- 炸弹(有些地方叫豹子) > 同花顺 > 同花 > 顺子 > 对子 > 散牌
- 同类型的组合先比较最大的牌的点数. 然后是第二大的点数, 然后是第三大的点数, 最后才是比较花色,同样也是从最大牌开始
- 最大的顺子是A K Q , 最小的顺子是 A 2 3 , 同花顺也是同样道理
- 对子先比较的成对的点数,其次是散牌的点数,然后是成对的花色,最后是散牌的花色
- 这两个百分比的意思是这样的, 第一个百分比是指这三张牌的组合在所有可能的组合中所超过的比例. 第二个百分比的意思是实际牌局中, 他超过的所有不含有这三张牌之外的所有场景的个数. 这两个百分比相差很小.
- 主要的判断逻辑在Hand类中,界面代码非常简单 , 一共六个文件,可以直接编译运行
