Challenge Problems
Push your limits with challenges.
Question 1
Design a DFA that recognizes the language of strings containing an even number of 'a's. Explain how youβd determine the states and transitions.
π‘ Hint: Think about how many 'a's you would have processed as you move through states.
Question 2
Using the Pumping Lemma, show that the language L = {a^n b^n | n β₯ 0} is not regular.
π‘ Hint: Identify how the structure of the string changes with varying sizes of y.
