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

#include <bits/stdc++.h>
using namespace std;
 
int main() {

  int N;
  cin >> N;
  
  int f=0;
  
  for(int i=0;i<9;i++){
	if(N==0)
      break;
    f += N%10;
    N = N/10;
  }
  if(N%f==0)
    cout << "Yes" << endl;
  else
    cout << "No" << endl;
}
