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
Give a Context Free Grammar (CFG) for the following language: L = { w | the number of a’s and the number of b’s in w are equal, ∑= {a, b} }
Give cfg for the following language over {0,1} {w | w contains the substring 011}
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.
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) ....
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.
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...
