The minimum length of the string is 2, the number of states that the DFA consists of for the given language is: 2+1 = 3 states. Why is sending so few tanks to Ukraine considered significant? 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). Share Cite Improve this answer Follow answered Feb 10, 2017 at 9:59 Its a state like all the other states. The minimum possible string is 01 which is acceptable. Use functions to define various states. This means that we can reach final state in DFA only when '101' occur in succession. Connect and share knowledge within a single location that is structured and easy to search. For each character in the input set, each state of DFA redirects to another valid state.DFA Machine: For the above problem statement, we must first build a DFA machine. 0 and 1 are valid symbols.
