Give a formal proof that the regular languages are closed under complement by
constructing a DFA that accepts the complement language.
In class we constructed a NFA to accept the set of all binary strings where the 3rd
symbol from the end is a 1. Construct the equivalent DFA.
Assume the alphabet is the set of binary characters. The set has an
even number of 0 s (zeros) and one or two 1s
Give a formal proof that the regular languages
