Consider the context-free grammar G = (V, T, S, P) where V = {S}, T = {0, 1, 2, +, *} and with productions S -> S + S | S * S | 0 | 1 | 2 a) Show that the grammar is ambiguous b) Give an equivalent unambiguous grammar.
1.) Consider the following grammar in which S, A, and B are nonterminal symbols and S is the start symbol. S → 1A | 0B A → A0 | 1B B → 10A| 1 Show that the grammar is ambiguous by showing two parse trees for the sentence 1110110 using leftmost derivation.

Consider a grammar: S --> | aS | SS SSb | Sbs, Where T={a,b} V={S }. Show that the grammar is ambiguous. What is the language generated by this grammar?
Consider a grammar: S --> | as SS SSb Sbs, Where T={a,b} V={S}. a. Show that the grammar is ambiguous. b. What is the language generated by this grammar?
6. (5 points) Consider the context free grammar G = (V, E, R, S) where V is {S, A, B, a, b,c}, & is {a,b,c}, and R consists of the following rules: S + BcA S B +a → A S + b A+S Is this grammar ambiguous? swer. Justify your an-
I would like to know if the following grammar for {c^m+n a^m b^n | m, n elementof N} is an LL(2) grammar. S rightarrow ccSbb | cSb | T; T rightarrow cTa | and Use the string ccab to justify your answer. If your answer is YES, mark the YES box and show the leftmost derivation for the string ccab in the blanks below the YES box. Otherwise, mark the NO box and show a derivation that would lead to...
Consider the grammar G = (V,Σ,R,E) with V = {E,T,F} and Σ = {a,+,∗,(,)}, having the rules E → E+T | T T → T∗F | F F → (E) | a Give leftmost derivations for each of the following: (a) a∗a+a∗a (b) a∗(a+a)∗a
9. Mark the best description (smallest language class) for each of the following lang • R if it is regular • C if it is context free, but not regular . N if it is "bigger than" context free You do not have to prove your answer. L = {www: we {a,b}"} L2 = {a" : n > 2, m < 5} L3 = {a"m : n + m is even } LA = {w:na(w) + no(w) = n(w)} Ls...
