All strings of the language ends with substring 01. The DFA will generate the strings that do not contain consecutive 1's like 10, 110, 101, etc. Thus, Minimum number of states required in the DFA = 4 + 1 = 5. Construct a DFA for the strings decided in Step-02. Thanks for contributing an answer to Computer Science Stack Exchange! In DFA, there is no concept of memory, therefore we have to check the string character by character, beginning with the 0th character. Making statements based on opinion; back them up with references or personal experience. In state q2, if we read either 0 or 1, we will go to q2 state or q1 state respectively. The input set of characters for the problem is {0, 1}. Draw a DFA for the language accepting strings starting with '101' over input alphabets = {0, 1} Solution- Regular expression for the given language = 101 (0 + 1)* Step-01: All strings of the language starts with substring "101".

To gain better understanding about Construction of DFA, Next Article- Construction of DFA | Type-02 Problems. Moreover, they cannot be the same state since 1101 is in the language but 1011 is not. You could add a self-loop to q3 so that the automaton stays in q3 if it receives more 1s and 0s. First like DFA cover the inputs in the start There is slight change than DFA, we will include the higer bound and then we will go ahead with the actual input Means we will go on state A for input 'a'/'b' and then also we will go to state B on input 'a' As the string ends with 'a' and then if anything comes up we are not worried as it is not DFA. Affordable solution to train a team and make them project ready.
