R is a regular expression if R is– a, for some a ∈Σ– ε, the empty string– Ø, the empty set– (R1 ∪ R2), where R1 and R2 are reg. exprs.– (R1° R2), where R1 and R2 are reg. exprs.– (R1*), where R1 is a regular expression
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
