First, make DfA for minimum length string then go ahead step by step. Therefore, Minimum number of states in the DFA = 3 + 2 = 5. After reaching the final state a string may not end with 1011 but it have some more words or string to be taken like in 001011110 110 is left which have to accept that's why at q4 if it accepts 0 or 1 it remains in the same state. Therefore, Minimum number of states in the DFA = 3 + 2 = 5. 3 strings of length 3 = {101, 010,no more string} . How to deal with old-school administrators not understanding my methods?

Asking for help, clarification, or responding to other answers. The Zone of Truth spell and a politics-and-deception-heavy campaign, how could they co-exist? Clearly 110, 101 are accepting states. Example 3: Design an NFA with = {0, 1} in which double '1' is followed by double '0'. For this, make the transition of 0 from state "A" to state "B" and then make the transition of 1 from state "B" to state "C" and notice this state "C" as the final state.

This means that we can reach final state in DFA only when '101' occur in succession. Experts are tested by Chegg as specialists in their subject area. The minimum possible string is 01 which is acceptable. 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). This FA will consider four different stages for input 0 and input 1. All strings starting with n length substring will always require minimum (n+2) states in the DFA. q1: state of odd number of 0's and even number of 1's.
