Niven Number Program - ICSE 2016 Computer Science

Write a program to accept a number and check and display whether it is a Niven number or not.

Niven number is that number which is divisible by its sum of digits.

Example:
Consider the number 126.
Sum of its digits is 1 + 2 + 6 = 9, and 126 is divisible by 9.

Java 

import java.util.Scanner;
class Niven{
    public static void main(String[] args){
        Scanner in = new Scanner(System.in);
        System.out.print("Enter the number: ");
        int n = Integer.parseInt(in.nextLine());
        int sum = 0;
        for(int i = n; i != 0; i /= 10)
            sum += i % 10;
        if(n % sum == 0)
            System.out.println("Niven number");
        else
            System.out.println("Not a Niven number");
    }
}

Output

 
 OUTPUT : 
Enter the number: 126
Niven number
