Question 1
Construct the DFA for L = {a^n b^n | n≥0} and then derive its complement's DFA. Explain your steps.
💡 Hint: Pay attention to how the accepted patterns shift with the complement.
Question 2
Using the Pumping Lemma, demonstrate why the language L = {a^n b^m | n ≠ m} is not regular and relate this to its complement.
💡 Hint: Consider scenarios in which n and m are manipulated by the Pumping Lemma.
