Questions & Step-by-Step Solutions
Which parsing technique is generally more powerful, LL or LR?
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 LL parsing. LL parsing reads input from Left to right and produces a Leftmost derivation of the sentence.
Step 3: Learn about LR parsing. LR parsing reads input from Left to right and produces a Rightmost derivation in reverse.
Step 4: Compare the capabilities of LL and LR parsing. LL parsers can handle a limited set of grammars, while LR parsers can handle a wider range of grammars, including some that LL parsers cannot.
Step 5: Conclude that LR parsing is generally more powerful than LL parsing because it can process more complex grammatical structures.
