What are some examples of context-free languages and how are they different from other types of languages?
Context-free languages are a type of formal language in theoretical computer science. Examples include programming languages like C, Java, and Python. These languages are different from regular languages and context-sensitive languages because they can be described by context-free grammars, which have rules that do not depend on the context in which a symbol appears. This allows for simpler parsing and analysis of the language's syntax.
