Consider the following language over = {a,b,c}: L = {anncn|n20}. The following PDA P does not recognize L: X

Consider the following language over = {a,b,c}: L = {anncn|n20}. The following PDA P does not recognize L: X 90 a, ; a q1 E, E; E b, a; E q2 q3 a) What is L(P) instead? Give a precise description. Hint: It accepts every string in L but also some strings not in L. b) Use the CFL pumping lemma to prove that no PDA recognizes L. 94 95
