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]. WebThe DFA accepts w if the path ends in a final state. Otherwise the DFA rejects w.
