Problem 2 (Pumping Lemma) [8 points) Use the Pumping Lemma to show that the language L (abm | e, m 2 0 and l 2 m] is not regular. Problem 3 (Problem 1.49 in the tertbook) (6 points] (a) Let L -(ay y E (a, b and y contains at least n letters a, for n 2 1). Show that L is a regular language. (b) Let L = {any | y E {a, b)" and y contains at most n letters a, for n > 1). Show that L is not a regular language
