Study Notes
Regular expressions are patterns that specify a set of strings required for a particular purpose. They can be used to describe a finite set of strings in a concise way, and provide operations such as Boolean "or", grouping, quantification, and wildcard. These constructions can be combined to form arbitrarily complex expressions. Regular expressions describe regular languages in formal language theory, and have the same expressive power as regular grammars. They consist of constants and operator symbols, and the most common operations are concatenation, alternation, and Kleene star.
