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

		int reg=0;
		int num2 = sc.nextInt();

		int reg2=0;
		for(reg=0;num>0;reg++){
			if(num%10==0&&num>=10){
				while(num%10==0){
					num/=10;
				}
			}
			if(num>0){
				num--;
			}
		}
		if(num2%reg==0){
				reg2=1;
		}
		if(reg2==1){
			System.out.println("Yes");
		}else{
			System.out.println("No");
