(20 pt.) Prove that the class of regular languages is closed under reverse. That is, show that if ? is a regular language, then ?? = {?? | ? ∈ ?} is also regular.
Hint: given a DFA ? = (?, Σ, ?, ?0, ?) that recognizes ?, construct a new NFA ? = (?′, Σ, ?′, ?0′, ?′)that recognizes ?? and justify why your construction is correct.
