PreviousDesign deterministic finite automata for the set of strings over the alphabet \{a, b\} containing at least three occurrences of three consecutive b's, overlapping permitted (e.g., the string bbbbb should be accepted).NextAssume that a regular language L is provided to you as a DFA M(\{Q, \Sigma, \delta, q_0, F\}). How would you check whether L is infinite?
