Simple:

\(|\)|\d{n}

replace n with the number of digits you need. If you need to match a complete string, then put parentheses around the expression and prepend ^ and append $.

I believe this will work for you. It matches strings with n numbers or strings like "(" or ")". Exmpl.: for n = 2 it matches strings like "12", "22" ....

^([0-9]{n})$|^([()]{1})$
