Primes
Statement
Goal
Your mission is to find the average of primes between 2 to N (including N).NOTE: If the number is not an integer you need to round it.
For example: N = 7
(2+3+5+7) / 4 = 4.25
4.25 isn't integer so the output is: 4
Input
N: an integer
Output
The average of primes between 2 to N (including N).
NOTE: If the number is not an integer you need to round it.
