WebThe DFA accepts w if the path ends in a final state. Otherwise the DFA rejects w. The language of a DFA is the set of accepted strings. Example. The example DFA accepts the strings a, b, ab, bb, abb, bbb, …, abn, bbn, …. So the language of the DFA is given by the regular expression (a + b)b*. Start 0 1 2 a b a b a b Start 0 1 2 a, b a b a, b

It appears that your NFA is correct, so if you convert that to a DFA and minimize it you should get your original DFA (though it would be tedious to do by hand). Don't worry about the fact that there different ways to do the NFA to DFA construction: either will work. $\endgroup$ irish sea forecast tomorrow
