    //   Given below is a class with the following specifications
    //   Class Name: Equivalent
    //   Data members: int n – to store first number
    //   int m – to store the second number
      
    //   Member methods:
    //   1. A parameterised constructor to initialise values to member
    //   variables.
    //   2. int sumFactor(int num)- to return factors sum excluding
    //   number as its factor.
    //   3. check()- A function to check whether number is an equivalent
    //   number or not.
      
    //   Equivalent numbers are numbers where the factors sum(other than the
    //   number itself) are identical.Ex 159 and 559 are equivalent numbers
    //   since their factors sum is same.
    //   159=1,3 and 53= 1+3+53=57
    //   559=1,13 and 43=1+13+43=57
