Given an integer N, the task is to check whether the number is divisible by the sum of its digits or not. If divisible, then print “YES” else print “NO”.

**Examples:**

Input:N = 12Output:YESExplanation:As sum of digits of 12 = 1 + 2 = 3 and 12 is divisible by 3 So the output is YESInput:N = 123Output:NO

**Approach:** The idea to solve the problem is to extract the digits of the number and add them. Then check if the number is divisible by the sum of its digit. If it is divisible then print YES otherwise print NO.

Below is the implementation of above approach:
