华为面试题：扑克牌大小 C语言源码

扑克牌游戏大家应该都比较熟悉了，一副牌由54张组成，含3~A、2各4张，小王1张，大王1张。牌面从小到大用如下字符和字符串表示（其中，小写joker表示小王，大写JOKER表示大王）：
3 4 5 6 7 8 9 10 J Q K A 2 joker JOKER
输入两手牌，两手牌之间用"-"连接，每手牌的每张牌以空格分隔，"-"两边没有空格，如：4 4 4 4-joker JOKER。
请比较两手牌大小，输出较大的牌，如果不存在比较关系则输出ERROR。
基本规则：
（1）输入每手牌可能是个子、对子、顺子（连续5张）、三个、炸弹（四个）和对王中的一种，不存在其他情况，由输入保证两手牌都是合法的，顺子已经从小到大排列；
（2）除了炸弹和对王可以和所有牌比较之外，其他类型的牌只能跟相同类型的存在比较关系（如，对子跟对子比较，三个跟三个比较），不考虑拆牌情况（如：将对子拆分成个子）；
（3）大小规则跟大家平时了解的常见规则相同，个子、对子、三个比较牌面大小；顺子比较最小牌大小；炸弹大于前面所有的牌，炸弹之间比较牌面大小；对王是最大的牌；

（4）输入的两手牌不会出现相等的情况。
