Questions & Step-by-Step Solutions
Which of the following is a key advantage of LR parsing over LL parsing?
Step 1: Understand what LR parsing is. LR parsing is a bottom-up parsing technique that reads input from left to right and produces a rightmost derivation in reverse.
Step 2: Understand what LL parsing is. LL parsing is a top-down parsing technique that also reads input from left to right but produces a leftmost derivation.
Step 3: Learn about left recursion. Left recursion occurs when a grammar rule refers to itself as the first symbol on the right side of the rule.
Step 4: Recognize that LR parsing can handle left recursion. This means it can process certain types of grammars that LL parsing cannot.
Step 5: Conclude that the key advantage of LR parsing over LL parsing is its ability to handle left recursion.
