Semi-Perfect/Pseudo Perfect Number in Java


Question : Write a program to accept a number and check whether it is Semi-Perfect number or not.


Semi-Perfect Number : A Semi-Perfect number or Pseudo-Perfect number is a natural number n that is equal to the sum of all or some of its proper divisors.


A Semi-Perfect number that is equal to the sum of all its proper divisors is a perfect number.


First few Semi-Perfect numbers are: 6, 12, 18, 20, 24, 28, 30, 36, 40 etc.

Example :-

Input : 6

Proper Divisors of 6 : 1, 2, 3

Sum of Proper Divisors : 1 + 2 + 3 = 6

Output : Semi-Perfect Number (Since sum of all the factors is equal to the number, it is also a Perfect Number).


Input : 12

Proper Divisors of 12 : 1, 2, 3, 4, 6

Sum of Proper Divisors : 1 + 2 + 3 + 6 = 12

Output : Semi-Perfect Number
