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 JavaScript (node.js v5.12) (judge verdict: Accepted)

function main(input) {
  var numStr = input.toString(10)
  var num = 0;
  for(var i = 0; i < numStr.length; i = i + 1) {
    num += Number(numStr.slice(i, i + 1))
  }
  if(input % num == 0) {
    console.log("Yes")
  } else {
    console.log("No")
  }
}
main(require('fs').readFileSync('/dev/stdin', 'utf8'));
