Implement regular expression matching with support for ‘.’ and ‘*’. ‘.’ Matches any single character. ‘*’ Matches zero or more of the preceding element. The matching should cover the entire input string (not partial). The function prototype should be: bool isMatch(const char *s, c...
10. Regular Expression Matching #1 动态规划[AC] 在正则表达式中,由于不同的字符会有不同的匹配规则,其中.和*比较特别,需要对这两类字符进行分类讨论。 定义状态dp[i][j]表示输入串长度为i,模式串长度为j时,是否能匹配。 初始化状态值: 输入串为空,模式串为空: dp[0][0]必然可以匹配,即dp[0][0]=...
10. Regular Expression Matching 题目描述(困难难度) 一个简单规则的匹配,「点.」代表任意字符,「星号*」 代表前一个字符重复 0 次或任意次。 解法一 递归 假如没有通配符 * ,这道题的难度就会少了很多,我们只需要一个字符,一个字符匹配就行。如果对递归不是很了解,强烈建议看下这篇文章,可以理清一下递归...

If you have programmed in Perl or any other language with built-in regular-expression capabilities, then you probably know how much easier regular expressions make text processing and pattern matching. If you are unfamiliar with the term, a regular expression is simply a string of characters that...
