Question: ( 2 3 ) Let Sigma = { a , b } . Determine all possible DFAs having exactly two states, and briefly describe

(23) Let \Sigma ={a, b}. Determine all possible DFAs having exactly two states, and briefly describe
(in English) what language each one recognizes. You might find it helpful to write a program
to generate all of the DFAs. For DFAs, if neither is final the language is empty, and if both
are final the language is \Sigma ?, so you need only consider the cases when there is exactly one
final state.
