Introduction to Regular Expressions and Equivalence to Finite Automata

Regular expressions (REs) are used to describe languages by algebra and are equivalent to finite automata. They define regular languages precisely using operations like union, concatenation, and Kleene star. The concatenation of languages combines strings from two languages, while the Kleene star re
