text pattern matching

A regular expression, which is an object that describes the character pattern. The RegExp class for JavaScript represents regular expressions, and both string and RegExp define methods, which use regular expressions for powerful pattern matching and

Pattern matching function The most powerful functions in the string library are: Copy Code code as follows: String.find (String lookup) String.gsub (Global string substitution) String.gfind (Global string lookup) String.gmatch (

1 OverviewThe greedy and non-Greedy modes affect the Matching Behavior of the Child expressions modified by quantifiers. The greedy mode matches as many expressions as possible on the premise that the entire expression matches successfully, the

Regular Expression (Regular Expression) pattern matching can automate many text processing operations, such as search replacement, input verification, text conversion, and filtering. The powerful Regular Expression Processing Engine greatly reduces

This article focuses on the algorithms that are extended from the Rabin-Karp Algorithm to the two-dimensional algorithm to solve the two-dimensional pattern matching problem. Problem:Search for a given m1 * M2 pattern in the composition of a N1 * N2
