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: Wrong Answer)

#include <stdio.h>


int main(int argc, char **argv)
{
  //読み込み
  int n;
  scanf("%d",&n);
  //sの計算
  int xxx,s;
  xxx = 1;
  s = 0;
  while(xxx == 1){
    s += n % 10;
    n = n / 10;
    if(n == 0){
      xxx = 0;
    }
  }
  //割り切れるかどうか
  if(n % s == 0){
    printf("Yes\n");
  }
  else{
    printf("No\n");
  }
  return 0;
}
