Context-Free Language

A context-free language is a set of strings generated by a type of grammar where the rules used to produce each symbol or group of symbols don't depend on the surrounding symbols. Think of it as a structured way to create sequences (like sentences or code) where each part can be replaced or expanded independently according to defined rules. This concept is fundamental in computer science for designing programming languages and parsing algorithms, as it allows for systematic and predictable construction and analysis of complex sequences without considering their broader context.
