WebOct 10, 2024 · It can be followed by any string in L to get a string in L. Call its state [e]. The string a is distinguishable from the empty string, as it can be followed by aaL + L to get a string in L. Call its state [a]. The strings b and c are likewise distinguishable and have states [b] and [c]. WebFor the rest, you should show that your DFA is minimal (it is). 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. $\endgroup$
