Fantastic numbers are those natural numbers whose sum of divisors excluding them selves is equivalent for the selection alone, i.e., if we work out the sum of divisors of a range excluding alone and it comes out to get similar to the original amount, then that selection is referred to as a Perfect Numbers.
A computable selection, also referred to as recursive number, is a true amount these kinds of that there exists an algorithm which, provided a beneficial quantity n as input, provides the primary n digits with the computable amount's decimal illustration.
