Question: L = { w in { a , b } * * | w | | has exactly one a and at least one b

L={w in {a,b}**|w|| has exactly one a and
at least one b}. This language is the
intersection of two simpler languages.
Construct DFAs for the two simpler
languages first, then combine to
construct the DFA for the original
language L.
L = { w in { a , b } * * | w | | has exactly one
