Similarly, from 2nd, 3rd and 4th state, there are 24 possible transitions for each state i.e. we have 24∗24∗24∗24=216 possible transitions. Each state also has 2 possibilities of being final state or not, so there are 24 possibilities for choosing final states. So total number of DFAs = 216∗24=220. flow switch wasser

Web6 feb. 2024 · 1 Answer. As pointed out in the comments, finding a DFA for compliment of the language of another DFA is quite straightforward: you simply make all accepting states non-accepting, and vice-versa.

On b, there is a transition from the accepting state to the non-accepting state. DFAs need all transitions and all states to be complete, unlike NFAs. – Welbog Jul 25, 2024 at 17:07 " - How many final states can a dfa have
