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

Solution in C (GCC 5.4.1) (judge verdict: Runtime Error)

#include <stdio.h>

int main(void){
  int n,s;
  int n2,i;
  int ten = 1;
  scanf("%d",&n);
  n2 = n;
  while(i < 9){
    ten = ten * 10;
    s = s + n2 % ten;
    n2 = n2 - (n2 / ten) * ten;
    i++;
  }
  if( n % s == 0)
    printf("Yes\n");
  else 
    printf("No\n");
  return 0;
}
