> 本题目中最大的陷阱:(唉!想想人家重蹈覆辙,好悲惨哦!所以写出来了!)
> 题目中有这样一句话All excuses can contain any upper or lower case alphanumeric character, a space, or any of the following punctuation marks [".,!?] not including the square brackets and will not exceed 70 characters in length. 
> 对这句话的理解要注意:can contain 是说可以包含这些,而不是只包含这些!所以嘛,excuses中还会有什么1,2,3,4,5这些数字,还有什么@#¥%%^&^&^&×&^×^&这些乱七八糟的符号!他们也是下文说的分割符!
> -----------------------------------------------
> 下文说分割符可以是: the beginning or end of the line or any non-alphabetic character or a space
> 汗!为什么space要独立于non-alphabetic character 之外呢?难道说space不算non-alphabetic character ?
> 为什么要单独说它泥?优点郁闷,忽悠人嘛!换成the beginning or end of the line or any non-alphabetic character 不就可以了么?还省那么多字呢!
> -------------------------------------------------
> 本题还有一个陷阱,这个陷阱还比较合理!大家就自己去想了!
