Problem Statement

Let S(n) denote the sum of the digits in the decimal notation of n.
For example, S(101) = 1 + 0 + 1 = 2.

Given an integer N, determine if S(N) divides N.

Constraints

1 \leq N \leq 10^9

Input

Input is given from Standard Input in the following format:

N

Output

If S(N) divides N, print Yes; if it does not, print No.

Sample Input 1

12

Sample Output 1

Yes

In this input, N=12.
As S(12) = 1 + 2 = 3, S(N) divides N.

Sample Input 2

101

Sample Output 2

No

As S(101) = 1 + 0 + 1 = 2, S(N) does not divide N.

Sample Input 3

999999999

Sample Output 3

Yes

import java.util.Scanner;

public class Main {

	public static void main(String[] args){
		Scanner sc = new Scanner(System.in);
		String s = sc.nextLine();
		int n = Integer.parseInt(s);
		
		int sum = 0;
		for(int i = 0; i < s.length(); i++) {
			int digit = Integer.parseInt(s.substring(i , i+1));
			sum += digit;
		}
		
		if((n % sum) == 0) {
			System.out.println("Yes");
		}else {
			System.out.println("No");
		}
		
	}
