Q2. Find a production of the form "A → , such that S → 0A, A → "produces (00) Q3. Let G be the phrase-structure grammar with vocabulary V (A,B, a, b, S], terminal element set T-(a, b), start symbol S, and production set P-(S → ABa, S → Ba, A → aB, AB → b, B → ab). Which of these are derivable from ABa? (1) ba, (2) abb, (3) aba, (4) b, (5) aababa

Consider the following grammar: A -> aB | b | cBB B -> aB | bA | aBb C -> aaA | b | caB Perform the pairwise disjoint test for the grammar. Rewrite the above grammar so that all grammar rules pass the pairwise disjoint test. Suppose lex() is the lexical analyzer which gets the next lexeme and puts its token code in the global variable nextToken. And suppose the token codes for terminals a, b, and c are...

Consider the following grammar for a language, where a and b are called terminals while <S>, <A> and <B> are called non-terminals, where <S> is the starting entity, i.e., from which we generate strings. The goal is to generate a sequence of as
