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

int main(int argc, char const *argv[]) {
  int n,x,i=0;
  scanf("%d",&n );
  x=n;
  for (i = 0; n > 10; i++) {
    n=n/10;
    ++i;
  }
  if (x%i!=0) {
    printf("No\n");
    return 0;
  }
  printf("Yes\n");
  return 0;
