Describe the process of designing a context-sensitive grammar for a language consisting of strings with an equal number of ones, twos, and threes.
Designing a context-sensitive grammar for a language consisting of strings with an equal number of ones, twos, and threes involves several steps and considerations. Context-sensitive grammars are a type of formal grammar that generate languages that can be recognized by linear-bounded automata. These grammars are more expressive than regular grammars and context-free grammars, as they
Give an example of a context-sensitive language and explain how it can be recognized by a context-sensitive grammar.
A context-sensitive language is a type of formal language that can be recognized by a context-sensitive grammar. In the Chomsky hierarchy of formal languages, context-sensitive languages are more powerful than regular languages but less powerful than recursively enumerable languages. They are characterized by rules that allow for the manipulation of symbols in a context-dependent manner,
