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 <stdio.h>

int unidade(int a, int b){
    return a%b;
}

int main(){
    int x,u[10];

    scanf("%d",&x);
    int c=0,f,fi;
    f=x;
    for(int i=10;f/i!=0;i=i*10){
        u[c]=unidade(f,i);
        f=f/i;
        c++;
        fi=i;
    }
    u[c]=unidade(f,fi);

    int soma=0;
    for(int d=0;d<=c;d++){
        soma=soma+u[d];
    }
    if((x%soma)==0){

        printf("YES\n");
    }
