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 Go (1.6) (judge verdict: Accepted)

package main

import (
	"fmt"
	"strconv"
	"strings"
	"unicode/utf8"
)

func main(){
	var s string
	len := utf8.RuneCountInString(s)
	fmt.Scanf("%s",&s)
	sl := make([]string,len)
	sl = strings.Split(s,"")
	sum := 0
	input, _ := strconv.Atoi(s)
	for i := range sl {
		a, _ := strconv.Atoi(sl[i])
		sum = sum + a
	}
	var ans string
	if (input % sum) == 0 {
		ans = "Yes"
		} else {
		ans = "No"
	}
	fmt.Println(ans)
}
