Agree This problem has been solved! I have a solution with more than one final state, but cannot come up with a solution which has only one final state. In other words, your language consists of strings with an odd number of 1 followed by 101 (because 101 does not change the "oddity" of the number of 1 s). To gain better understanding about Construction of DFA, Next Article- Construction of DFA | Type-02 Problems. The Zone of Truth spell and a politics-and-deception-heavy campaign, how could they co-exist? Therefore, Minimum number of states in the DFA = 3 + 2 = 5.
