Problem Statement

An integer X is called a Harshad number if X is divisible by f(X), where f(X) is the sum of the digits in X when written in base 10.

Given an integer N, determine whether it is a Harshad number.

Constraints

1?N?10^8

N is an integer.

Input

Input is given from Standard Input in the following format:

N

Output

Print Yes if N is a Harshad number; print No otherwise.

Sample Input 1

12

Sample Output 1

Yes

f(12)=1+2=3. Since 12 is divisible by 3, 12 is a Harshad number.

Sample Input 2

57

Sample Output 2

No

f(57)=5+7=12. Since 57 is not divisible by 12, 12 is not a Harshad number.

Sample Input 3

148

Sample Output 3

No

Solution in Java8 (OpenJDK 1.8.0) (judge verdict: Wrong Answer)

import java.util.Scanner;


class Main{

	public static void main(String args[]){

		Scanner scan = new Scanner(System.in);

		int N =  scan.nextInt();
		int M = N;
		int keta = String.valueOf(N).length();		//桁数が返されるは"+
		int m = keta;
		int sum = 0;			//合計値


		for(int j = 0;j < m;j++){
			int waru = 1;
			if(keta != 0){
				for(int i = keta-1;i > 0;i--){
					waru *= 10;
					
				}
			}
			
			sum += N/waru;
			
			keta--;
			N -= (N/waru)*waru;
			

		}
		
		
		if(M%sum == 0){
			System.out.println("Yes");

		}else{
			System.out.println("NO");
		}

	}
