WebA regular expression can be defined as a language or string accepted by a finite automata. We know that a finite automata consists of five touples {Q, Σ, δ, q 0, F }. Among them a Regular Expression is a string on Σ, i.e. it will consist only with input alphabets. In short a Regular Expression is written as RE.
