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 C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>
#include <stdlib.h>

void harshadC(char *p)
{
  int sum=0,i;
  char c;
  for(i=0; *(p+i) != '\0'; i++)
  {
    c = *(p+i);
    sum = atoi(&c) + sum;
  }

  if( (atoi(p) % sum) == 0 && atoi(p) > sum)
  {
    printf("Yes\n");
  }else
  {
    printf("No\n");
  }
}

int main(void)
{
  int n;
  char line[128];

  fgets(line, 128, stdin);
  harshadC(line);

}
