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);
        int N = sc.nextInt();
        int order = String.valueOf(N).length();
        int sum = 0;
        double Rr = N;
        for (int i = 0; i < order - 1; i++) {
            Rr /= 10;
        }
        
        double a;
        for (int i = 0; i < order; i++) {
            a = Math.floor(Rr);
            
            sum += a;
            Rr = Rr - a;
            Rr *= 10;
        }
        
        System.out.println(N % sum == 0 ? "Yes" : "No");
    }
