To construct an NFA for the language L = ( a b ∗ a a + b ( b a ) ∗ ) L = (ab^*aa + b(ba)^*) , we can follow similar steps as before, using closure properties to combine simpler NFAs. a b ∗ a a ab^*aa This part of the language matches strings that start with 'a', followed by zero or more 'b's, and end with 'aa'. The regular expression for this part is a b ∗ a a ab^*aa The corresponding NFA for this part can be constructed as follows: b ( b a ) ∗ b(ba)^* This part of the language matches strings that start with 'b' and are followed by zero or more occurrences of 'ba'. The regular expression for this part is b ( b a ) ∗ b(ba)^* . The corresponding NFA for this part can be constructed as follows: Combined NFA : Combine the NFAs for a b ∗ a a ab^*aa and b ( b a ) ∗ b(ba)^* into a single NFA. Add a new initial state q s q_s and ε-transitions from q s q_s to the initial states of both NFAs. Make the initial states of both NFAs non-initial. Make the final states of both NFAs non-final and add ε-transitions from their original final states to a new final state q f q_f q f . Putti
