WebIf L1 is a CFL, then L⁄ 1 is a CFL. Proof 1. Let L1 be generated by the CFG, G1 = (V1;T1;P1;S1). 2. Without loss of generality, subscript each nonterminal of G1 with a 1. 3. Define the CFG, G, that generates L⁄ 1 as follows: G = (V1 [fSg;T1;P1 [fS ! S1S j Λg;S). 4. Each word generated is either Λ or some sequence of words in L1. 5. Every ... WebJun 28, 2024 · Solution : (A) is correct because for ambiguous CFL’s, all CFG corresponding to it are ambiguous. (B) is also correct as unambiguous CFG has a unique parse tree for each string of the language generated by it. (C) is false as some languages are accepted by Non – deterministic PDA but not by deterministic PDA. ...
