LR(k) Grammar

LR(k) grammar is a way to describe how a computer can analyze and understand the structure of a formal language, such as programming languages. "LR" stands for Left-to-right parsing with a Rightmost derivation in reverse, meaning the parser reads input from start to finish, making decisions based on the current and previous symbols. The "(k)" indicates it looks ahead k symbols in the input to decide how to parse. LR(k) grammars are used in designing precise and efficient parsers that can handle complex language constructs, ensuring code is syntactically correct before translation or execution.
