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.*;

public class Main {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		String num = sc.next();

		String sub;

		int sum = 0;
		for (int i = 0; i < num.length(); i++) {
			sub = num.substring(i, i + 1);
			sum += Integer.parseInt(sub);
		}
		String s;
		int n = Integer.parseInt(num);
		if (n % sum == 0) {
			s = "Yes";
		} else {
			s = "No";
		}
		// 出力
		System.out.println(s);
	}
