Describe the theorem that a language L is recognized by a DFA if and only if L is illustrated by a regular expression.
Proof the theorem that the class of regular languages is closed under union; that is, if L_{1} is recognized by a NFA and L_{2} is recognized by a NFA, then L_{1} υ L_{2} is recognized by a NFA as well.
Let REGEXP be the language of valid regular expressions over {a, b}. That is, REGEXP is the set of all strings over the symbols Σ= {a, b, (,), U,*, ^} that are valid regular expressions. For example, the string “a (a U b)" is in REGEXP, whereas the string
