# Harshad Number or Niven Number

Problem to find the Harshad Number or not in given number.

If given number is completely divisible by sum of the each and every digit value , So It's Harshad Number or Niven Number.

## Example-1:

Input : n = 2020 Output : Harshad Number Explain : 2+0+2+0 = 4. The number 2020 is completely divisible by 4. So it is "Harshad Number".

## Example-2:

Input : n = 17 Output : Not a Harshad Number Explain : 1+7 = 8. The number 17 is not divisible by 8. So it is "Not a Harshad Number".

# Solution

public class Main { public static void main(String [] args) { int num = 2020; int sum = 0, t = num; while(t!=0) { sum = sum + (t%10); t = t/10; } if(num % sum == 0) { System.out.print("Harshad Number"); } else { System.out.print("Not a Harshad Number"); } } }

n = 2020 k = 0 for x in str(n): k += int(x) if(n % k == 0): print("Harshad number") else: print("Not a Harshad number")

## Output

Harshad number
