Find a CFG for the language with all words that start with a letter "a" or are of the form anb2n, n = 1, 2, 3, ... a) S-> aS | aSbb | null b) It is impossible to build such a CFG. c) S-> aS | abbS | null d) None of the above is correct. e) S-> aX; X->aX | bX | null
Automata theory Q1: Assume S = {a, b}. Build a CFG for the language of all strings with a triple a in them. Give a regular expression for the same language. Convert the CFG into CNF grammar. Q2: Assume S = {a, b}. Build a CFG for the language defined by (aaa+b)*. Convert the CFG into CNF grammar. Q3: Explain when a CFG is ambiguous. Give an example of an ambiguous CFG. give vedio link also
I have below questions with answer! what if we get different question: Write a CFG without empty rules that generates the language: L = strings from (a ∪ b)*c* where the number of a's and b's together is equal to the number of c's. Answer: S → Asc | ε A → a | b ================================================== Write a CFG without empty rules that generates the language: L = strings from (ab ∪ cb)*c* where the number of a's and b's...

Consider the given CFG: S ⟶ a X a X a , X ⟶ a X | b X | Λ What is the language this CFG generates? a) a language with all strings of at least 3 a's b) a language with all strings of a's and b's c) a language with all strings that start and end with a's with at most 3 a's d) a language with all strings of at most 3 a's e) None of...
Give a CFG that generates the language L(a*b*c*) \ { anbncn | n is a non-negative integer }. This question is quite challenging; you will first need to devise a good strategy for how the CFG should work and then create the CFG to implement the strategy. You might want to do the other questions first. No messy writing please.
Hello, I need help solving these two computer science questions. 3. Give a CFG for each of the following: (a) The language {0416 with a +b}. (b) All binary palindromes with exactly three 1's (such as 001010100). 4. Consider the following CFG with start state S: SOAS 1BS € A → OAA 1 B + 1BBO Determine the language generated by S. Justify your answer.
Given a language A= {0^(2n) 1^(n+1) | n >= 0} Please answer the following questions. Provide a context free grammar
Please Answer Question#02 Solution of Question 1 is attached. Solution of Questions #01 Please do Questions #01 As soon as possible. = {a, b} will be used for all of the following exercises. The alphabet 1. Give regular expressions which exactly define the following languages. [7 marks] (a) L1 which has exactly one b but any number of as. (b) L2 which has an even number of as and an even number of bs. [7 marks] (c) L3 which contains...
