LR parser

An LR parser is a type of computer program used in language processing, particularly in understanding and analyzing programming languages. It reads the code from left to right and uses a set of rules to determine the structure and meaning of the code. The "LR" stands for "Left-to-right" reading and "Rightmost derivation," meaning it efficiently processes input by making the most informed decisions about the code’s structure as it goes. This helps in accurately translating programming instructions into a form the computer can execute, ensuring the code works correctly and reliably.
