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.
Input is given from Standard Input in the following format:
N
Print Yes
if N is a Harshad number; print No
otherwise.
12
Yes
f(12)=1+2=3. Since 12 is divisible by 3, 12 is a Harshad number.
57
No
f(57)=5+7=12. Since 57 is not divisible by 12, 12 is not a Harshad number.
148
No
