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 PHP (5.6.30) (judge verdict: Accepted)

<?php
$number=trim(fgets(STDIN));
$wNumber=$number;

$digitSum=0;

while($number>0){
    $digitSum+=$number%10;
    $number/=10;
}

if ($wNumber%$digitSum==0){
    echo "Yes";
}else{
    echo "No";
}
