WebThe DFA has six states: q0, q1, q2, q3, q4, and q5. The start state is q0, which represents the initial state of the DFA when it starts reading an input string. The accepting state is q5, which represents a state where the DFA ends up if it has successfully recognized the input string as a valid member of the language L. WebJun 28, 2024 · The NFA of the language containing all the strings in which 2nd symbol from the RHS is “a” is: Here, A is the initial state and C is the final state.

WebIn DFA we have to take care of all the input alphabets at every state. so we have to take care of input symbol ‘b’ on state A, that is we made self-loop on start state. On state B if a comes then we will accept it as repetition of ‘a’ after a will not ruin anything . Because we want ab in the end.
