Question: Unless stated otherwise, the base alphabet in this problem set is = {(a,b). 1. Tricky: The language L = {w | w contains as many

Unless stated otherwise, the base alphabet in this problem set is = {(a,b). 1. Tricky: The language L = {w | w contains as many occurrences of the substring ab as occurrences of the substring "ba} is regular. Prove it by giving an FA (deterministic or non-deterministic) for L. Explain why this FA accepts this language. [1] Examples: accepted: aba, baaabab not accepted: abb, abababab 2. Give a DFA for all strings that have an even number of as and an odd number of bs. [22]
