Problem Statement

Let S(n) denote the sum of the digits in the decimal notation of n.
For example, S(101) = 1 + 0 + 1 = 2.

Given an integer N, determine if S(N) divides N.

Constraints

1 \leq N \leq 10^9

Input

Input is given from Standard Input in the following format:

N

Output

If S(N) divides N, print Yes; if it does not, print No.

Sample Input 1

12

Sample Output 1

Yes

In this input, N=12.
As S(12) = 1 + 2 = 3, S(N) divides N.

Sample Input 2

101

Sample Output 2

No

As S(101) = 1 + 0 + 1 = 2, S(N) does not divide N.

Sample Input 3

999999999

Sample Output 3

Yes

Solution in JavaScript (node.js v5.12) (judge verdict: Runtime Error)

"use strict"

function main(input) {

    let num = Number(input)
    n = input.length
    let tmp = num
    let ans = 0
    for (let i = 1; i <= n; i++) {
        ans += num % 10
        tmp = Math.floor(tmp / 10)
    }
    if (num % ans == 0) console.log('Yes')
    else console.log('No')
}
main(require('fs').readFileSync('/dev/stdin', 'utf8'));
