题目:(这题好难.题目意思类似于第十题,只是这里的*就是可以匹配任意长度串,也就是第十题的‘.*’)'?' Matches any single character. '*' Matches any sequence of characters (including the empty sequence). The matching should cover the entire input string (not partial). The function prototype should…

开篇 通常的匹配分为两类,一种是正则表达式匹配,pattern包含一些关键字,比如'*'的用法是紧跟在pattern的某个字符后,表示这个字符可以出现任意多次(包括0次). 另一种是通配符匹配,我们在操作系统里搜索文件的时候,用的就是这种匹配.比如 "*.pdf",'*'在这里就不再代表次数,而是通配符,可以匹配任意长度的任意字符组成的串.所以"*.pdf"表示寻找所有的pdf文件. 在算法题中,往往也会有类似的模拟匹配题,当然考虑到当场实现的时间,会减少通配符数量…
