For each of these languages, give both a context-free grammar and a push down automaton. Briefly explain how your CFG and PDA work. Your CFG should be relatively simple and contain at most 6 variables. For this question, your PDA cannot be directly convertedfrom your CFG (a)L1={ x#y | x is a prefix of yR, and y∈{a,b}* } ,Σ ={a,b,#} Recall that wR is w written backwards, and u is a prefix of v if v=ut for some stringt.For example bb#abb is in L1, but a#ab is not. (b)L2={ aibjck | i ≥ j or j ≥ k } (c)L3 = {w∈{a,b}* | w contains an unequal number of a’s and b’s}

We can write a context-free grammar (CFG) for it: S → 0A | 1S | aS | ε A → 0A | aS | ε Informally explain the two parts of the expression “all and only the strings.” How do we know that we get all the strings of L by this grammar? And, how do we know that we get only the strings of L by this grammar?

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Let G = (V, T, S, P) be the phrase-structure grammar with V = {0, 1, A, S}, T = {0, 1} and a set of productions P consisting of S → 1S, S → 00A, A → 0A, and A → 0. Identify the correct argument to show that 11001 does not belong to the language generated by G. Multiple Choice A) Every production results in a string that ends with S , A, or 0. Therefore, the string 11001, which ends with a 1, cannot be generated. B) Every production results in a string that does not contain S , A, or 0. Therefore, the string 11001, which contains 0, cannot be generated. C) Every production results in a string that starts with S , A, or 0. Therefore, the string 11001, which starts with a 1, cannot be generated. D) Every production results in a string that contains S , A, or 0. Therefore, the string 11001, which contains 1, cannot be generated.
