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: Accepted)

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner scanner = new Scanner(System.in);
		String input = scanner.next();
		//String input = args[0];
		
		int num = Integer.parseInt(input);
		
		
		int total = 0;
		for (int i = 0; i < input.length(); i++) {
			String string = input.substring(i, i+1);
			total += Integer.parseInt(string);
		}
		
		if (num%total==0) {
			System.out.println("Yes");
		}else{
			System.out.println("No");
		}
		
		scanner.close();
	}
