Chapter 15 Pattern Matching and Tries | 15.3

For example, to search for the pattern ‘a word followed with a space and followed with a number’, then the

regular expression becomes “\w+\s\d+”.

Here, the regular expression \w matches a word character, because the regular expression is with + symbol.

So, \w+ matches with one or more number characters.  en \s matches with a space character, and the \d+

matches with one or more number of digits.

15.4 FIXED PATTERN MATCHING ALGORITHMS

Various algorithms that are used to match a given pattern with the available patterns are discussed. Here, the

pattern that is to be matched is stable all through the search process.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.
