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 Python (3.4.3) (judge verdict: Accepted)

import math
N=int(input())
def g(N):#桁数を返す
  i=0#桁数
  while N>=1:
    N=N/10
    i+=1
  return i

def f(N):
  j=g(N)
  S=0
  while j!=0:
    d=math.floor(N/(10**(j-1)))
    S+=d
    N-=d*(10**(j-1))
    j-=1
  return S
  
if N%f(N)==0:
  print("Yes")
else: print("No")
