Prime checking
A number is considered prime if it’s only divisible by itself and by 1
(exactly two numbers).
Implement a function is_prime(n)
that would return True
if n
is prime and False
otherwise.
The input contains a single integer n
(1 ≤ n ≤ ).
The program should print Yes
if n
is prime and No
otherwise.
