Please build a CFG for a formal language with strings of the form 1^n0^(n+2)
Please prove that a formal language with strings of the form 1^n0^n can not be generated by FA (use Pumping Lemma)
Build PDA to generate all strings of the form 0 (n) 1 (2n+3) where n>=0 Build CFG to generate all strings of the form 0 (n) 1 (2n+3) where n>=0
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
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
can you plzz do question 1 and 2
Question 1. Design a CFG for the language over = {1, #} whose elements consist of every pair of distinct, #-separated unary values: L = {rı#x2 | 21, 22 € 1", 21 * x2}. Question 2. Design a CFG for the language of binary strings that contain at least one 1 in their second half: L = {uv | UE (OU 1)", v € OU 1)*1(0U 1)", [u '}. Question 3. This...
Please answer a-f
Answer all the following questions. (a) Find a CFG for the language defined by a' (b) Find a CFG for the language defined by b (c) Find a CFG for the language defined by a'b. (d) Find a CFG for the language defined by ab. (e) Find a CFG for the language defined by a"b2n. (f) Find a CFG for the language defined by an + b 2n.
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.
Input alphabet {a,b 1. write the CFG for the language of palindromes (5 points) 2. Convert this into PDA (state the accepting condition) (10 points) . Write a PDA for this language that satisfies the conditions required to convert it into CFG (5 points) 4. Convert the PDA from Q3 into CFG (10 points)
Input alphabet {a,b 1. write the CFG for the language of palindromes (5 points) 2. Convert this into PDA (state the accepting condition) (10 points) ....
Prove that the language given by the CFG below is not regular. S + PPQ P + OPPO | 1 Q +0000 1 Make sure that you give a formal proof with every step clearly erplained and justified with sentences (as seen in the tertbook), do not write just a sequence of mathematical erpressions.
Build a DFA that accepts the described language: The set of strings over {a, b} in which every a is either immediately preceded or immediately followed by b, for example, baab, aba, and b.
