In North America, phone numbers consist of three parts: ABB$-$CDD$-$ZZZZ where:

$$ ABB: the area code

$$ CDD: the exchange

$$ ZZZZ: the station code$/$line of the individual

Using regular expressions, you should further filter the phone numbers according to the following rules:

$1.$ The FIRST digit in the area code $($labeled $$A$$ in the pattern above$)$ CANNOT be a $1$ or a $0$
