My Submissions Question Solution Implement regular expression matching with support for'.'and'*'. '.' Matches any single character. '*' Matches zero or more of the preceding element. The matching should cover theentireinput string (not partial). The function prototype should be: bool isMatch(c...
PHP Regular Expressionalso known as regex are powerful pattern matching algorithm that can be performed in a single expression. Regular expressions use arithmetic operators such as (+,-,^) to create complex expressions. They can help you accomplish tasks such as validating email addresses, IP addre...

Description: Given an input string (s) and a pattern (p), 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). ...
Required substrings. Suppose you have an efficient way to check which of a list of strings appear as substrings in a large text (for example, maybe you implemented theAho-Corasick algorithm), but now your users want to be able to do regular expression searches efficiently too. Regular expre...
)will match onlya, and the second will matchbcd.By definition, whether an operator is greedy cannot affect whether a regular expression matches a particular string as a whole; it only affects the choice of submatch boundaries. The backtracking algorithm admits a simple implementation of non-...
Even so, a slow implementation of a linear-time algorithm can easily outperform a fast implementation of an exponential-time algorithm once the exponent is large enough. Testing a variety of popular regular expression engines on a so-called pathological regular expression demonstrates this nicely. ...
With the number of regular expression patterns increasing, the storage space of DFA expands rapidly, which decreases the hit rate of Cache and affect the matching performance ultimately. This paper presents an ef?cient regular expression grouping algorithm, which reduce the storage space of DFA ...
