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.

Given Input:
Expected Output:
Program:
Output:
import java.util.Scanner;
public class RAnsariNivenNumber
{
public void checkNiven() {
Scanner in = new Scanner(System.in);
System.out.print("Enter number: ");
int num = in.nextInt();
int orgNum = num;
int digitSum = 0;
while (num != 0) {
int digit = num % 10;
num /= 10;
digitSum += digit;
}
/*
* digitSum != 0 check prevents
* division by zero error for the
* case when users gives the number
* 0 as input
*/
if (digitSum != 0 && orgNum % digitSum == 0)
System.out.println(orgNum + " is a Niven number");
else
System.out.println(orgNum + " is not a Niven number");
}
}
