Transcribed Image Text:

Consider the language over Σ = {a,b,c} that is the concatenation of arbitrary palindromes of length at least 3 and occurrences of the substring abc: L = {x₁x₂...xk|k≥ 0, x₁ = abc or x = x, x₁ ≥ 3 for i = 1,..., k} . a) Give a CFG for L. b) Give a PDA for L. Although the generic CFG-PDA conversion will give you a correct answer, for full credit you should design a PDA directly using no more than 12 states.
