Questions & Step-by-Step Solutions
Which of the following parsing techniques can handle a larger class of grammars?
Step 1: Understand what parsing means. Parsing is the process of analyzing a string of symbols, either in natural language or in computer languages, to determine its grammatical structure.
Step 2: Learn about parsing techniques. There are different techniques for parsing, two of which are LR parsing and LL parsing.
Step 3: Know 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 4: Know what LL parsing is. LL parsing is a top-down parsing technique that reads input from left to right and produces a leftmost derivation.
Step 5: Compare the two techniques. LR parsing can handle more complex grammars than LL parsing.
Step 6: Understand the types of grammars. LR parsing can handle all deterministic context-free grammars, while LL parsing cannot.
Step 7: Conclude that LR parsing is more powerful than LL parsing in terms of the types of grammars it can handle.
