Is it possible to build DFA that support \d, \w, .(any symbol)? I understand that we can add each symbol from [0-9] as a separate edge for some of the symbols, but what about the others? for example .(any symbol)? or \S (not white space)?
In other words, can we build equivalent DFA for this NFA
(1) ---a----> (2) | | .(any symbol) | \/ (3)
