挑战：

给定两张五张牌，通过标准手牌排名确定哪一个获胜。

输入：

十张卡，它们之间用空格隔开，这些空格与stdin或用作命令行参数，以您更喜欢的形式为准。前五张牌是玩家1的手，后五张是玩家2的手。每张卡都是RS格式的两个字母字符串，其中R是等级，S是适合的。等级范围为2-9，T代表10，J，Q，K和A分别代表Jack，Queen，King和Ace。西装分别是H，D，C，S，分别代表Hearts，Diamonds，Club和Spades。您必须输出获胜玩家的号码：“ 1”或“ 2”。

卡示例：

AS - the Ace of Spades
QD - the Queen of Diamonds
2C - the Two of Clubs
TH - the Ten of Hearts

输入到输出示例：

5H 5C 6S 7S KD 2C 3S 8S 8D TD -> 2

说明：玩家1有一对5，而玩家2有一对8。

5D 8C 9S JS AC 2C 5C 7D 8S QH -> 1

说明：双方都没有什么特别的，但是玩家1的高牌是A，而玩家2的高牌是女王。

2D 9C AS AH AC 3D 6D 7D TD QD -> 2

说明：玩家1拥有三张A，玩家2拥有同花顺。

4D 6S 9H QH QC 3D 6D 7H QD QS -> 1

说明：两位玩家都有一对皇后区，但玩家1的第二高牌是9，而玩家2的是7。

规则和说明：

• 有关比较手牌的详细信息，请参阅扑克手的标准排名。
• 您可以假设每双手中没有重复的牌。
• 您可以假设每种情况下都有一定的赢家。
• 西装不影响手的排名。例如，两次不同花色的皇家同花顺是相等的（因此，根据上述规则，两个玩家都拥有皇家同花顺的任何输入均无效）。
• 因为这是代码高尔夫，所以最短的答案会获胜。

笔记：

• 与这个问题和这个问题有关。
• 基于欧拉计划问题54

我选择为代表每只手的每只手生成一个字符串，从用于手型的字符开始，然后是描述该类型的特定变体的字符（例如，哪张卡只有4张？），然后是如果出现平局，则剩余卡的值（如果两个玩家都具有相同的双对，则第5张卡将决定谁获胜）。我已经对它进行了广泛的测试，但是我实际上并不玩扑克，所以我希望我做对了。另外，我知道还没有打完高尔夫球，以后我可能会刮掉几十个字符。

Perl中，801 733个字符

我相信这是一个非常简单的实现。基本上，对于每只手，我们分别将西服和面孔分类。然后我们再制作一张ace数低的面孔副本，以便我们检查ace数低的直线。然后我们确定我们是否有同花或顺牌，以及高牌是什么。然后，我们只按得分顺序检查比赛（首先检查同花顺，然后检查四种），等等。实际得分只是手的类型的串联，其后依次是牌的面值（它们在重要版本中为_s（），在高尔夫球版本中为u（））。这里是：

@l{2..9,qw(T J Q K A)}=2..14;sub u{join"",map{$_>9?$_:"0$_"}shift,ref$_[0]?$$_[0]:map{$h[$_]}@_}sub e{$p[$_[0]-1]-1==$p[$_[0]]}sub f{@p=@_;e(1)&&e(2)&&e(3)&&e 4}sub h{$h[$_[0]]==$h[$_[1]]}sub i{h(@_[0,1])&&h @_[2,3]}sub t{@s=sort map{substr($_,1)}@_;$f=$s[0]eq$s[4];@l=@h=sort{$b<=>$a}map{$l{substr($_,0,1)}}@_;@l=(@l[1..4],1)while$l[0]==14;$s=0;if(f@l){$s=1;$h=$l[0]}else{$h=$h[0];$s=1 if f@h}$f&&$s?u 9,\$h:h(4,1)?u 7,4,0:h(3,0)?u 7,3,4:i(4,3,2,0)?u 6,0,4:i(4,2,1,0)?u 6,4,0:$f?u 5,0:$s?u 4,\$h:h(4,2)?u 3,4,0,1:h(3,1)?u 3,3,0,4:h(2,0)?u 3,2..4:i(4,3,2,1)?u 2,2,4,0:i(4,3,1,0)?u 2,1,4,2:i(3,2,1,0)?u 2,1,3,4:h(4,3)?u 1,4,0,1,2:h(3,2)?u 1,3,0,1,4:h(2,1)?u 1,2,0,3,4:h(1,0)?u 1,1..4:u 0,0..4}print t(@ARGV[0..4])gt t(@ARGV[5..9])?1:2
