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.
