We present a formalization of a matching algorithm for extended regular expression matching based on locations and symbolic derivatives which supports intersection, complement and lookarounds and ...

Plenty of analysts predicted a New York vs. Los Angeles meeting in the MLB postseason, but few projected it to happen sooner than the World Series. Thanks to a surprising late-season push from the New ...

这题用动态规划来做。 我们先看递归的思路。然后通过记忆化来优化。 我们的递归match(char[]s, char[] p, int ls, int lp)函数代表的是求s中长度为ls的字符串和p中长度为lp的字符串是否可以匹配。我们要求的答案就是长度都为各自字符串的长度是否匹配。 先看两种情况 ...

Abstract: Regular expression (RegEx)matching is a key function in network security, where matching of packet data against known malicious signatures filters and alerts against active network ...

A long time ago, I wrote a utility for an employer that allowed testers to perform verification on data coming out of a hardware box using a regular expression language. It allowed users to evaluate ...

When using the MPF you can use regular expressions to add functionality. You see this in application policies that let you filter file names and such. I came up with the idea for this post after I ...
