// THE PROBLEM
// ***************************
// The AdvancedArithmetic interface and the method declaration 
// for the abstract divisorSum(n) method are provided for you in the editor below.
// Complete the implementation of Calculator class, which implements the AdvancedArithmetic interface. 
// The implementation for the divisorSum(n) method must return the sum of all divisors of n.
