Consider the DFA M = (Q,Σ,δ,q1,F) where Q = {q1,q2,q3,q4},Σ = {a,b},F = {q4} andδ(q1,a) = q2,δ(q2,b) = q3,δ(q3,a) = q4,δ(q3,b) = q1.Convert this DFA to a regular expression using the method discussed in class (as this automaticallyproves that the answer is correct, as the algorithm is proven correct). You only need to calculate sub-expressions if it is necessary towards the final answer. Also, simplify each subexpression using any lawdiscussed in class (including those derived on the board). To summarize, those were 1) (ε+ R)∗= R∗,2) S ·R∗= R∗if L(S) ⊆L(R∗) and ε ∈S, and 3) S + R = R if L(S) ⊆L(R).
