Questions & Step-by-Step Solutions

What does LR stand for in LR parsing?
  • Step 1: Understand that LR parsing is a method used in computer science for analyzing the structure of text, like programming languages.
  • Step 2: Break down the abbreviation 'LR'. The 'L' stands for 'Left-to-right', which means the parser reads the input from left to right.
  • Step 3: The 'R' stands for 'Rightmost derivation in reverse', which means it constructs the parse tree starting from the rightmost part of the input and works backwards.
