Consider the following construction that converts a DFA, M = (Q, Sigma, delta, q_0, F), to a context-free grammar, G = (V, Sigma, R, S):
Consider the following construction that converts a DFA, M = (Q, Sigma, delta, q_0, F), to a context-free grammar, G = (V, Sigma, R, S): V = {V_i|q_i element Q}. That is, we make a separate variable V_i for each state q_i in Q. For each transition delta(q_i, a) = q_j we add a rule V_i rightarrowy aV_j to R. Additionally, we add a rule nu_i rightarrow epsilon for all q_i element F. That is, R contains |Sigma| .|Q| + |F| rules. S = V+0, where V_0 corresponds to the start state of M, q_0. Provide a formal proof showing that L(M) = L(G) for any DFA M
