Given a number N, you need to write a program that finds the sum of digits of the number till the number becomes a single digit and then check whether the number is Prime/Non-Prime.

Example 1:

Input:
N=5602
Output:
0
Explanation:
1st step=5+6+0+2=13
2nd step=1+3=4
Since 4 is not prime, so answer is 0.

Example 2:

Input:
N=12
Output:
1
Explanation:
1st step=1+2=3
Since, 3 is prime, so answer =1.

Your Task:
You don't need to read input or print anything.Your Task is to complete the function digitPrime() which takes a number N as input parameter and returns 1 if the final digit sum(adding digits until it becomes single-digit number) is prime.Otherwise, it returns 0.
