Here is a Python solution for the problem: ```python def is_prime(n): if n 2): return "NO" for i in range(3, int(n**0.5) + 1, 2): if n % i == 0: return "NO" return "YES" N = int(input()) print(is_prime(N)) ``` This program works by defining a function `is_prime(n)` that checks if a number `n` is prime. First, it checks if `n` is less than or equal to 1 or if it's an even number greater than 2. If either of these conditions are true, it returns "NO" because `n` is not a prime number. Then, it checks if `n` is divisible by any odd number up to the square root of `n`. If `n` is divisible by any of these numbers, it returns "NO" because `n` is not a prime number. If `n` passes both of these checks, it returns "YES" because `n` is a prime number. Finally, the program reads an integer `N` from the input, calls `is_prime(N)`, and prints the result.

Question

Here is a Python solution for the problem:

```python
def is_prime(n):
    if n <= 1 or (n % 2 == 0 and n > 2): 
        return "NO"
    for i in range(3, int(n**0.5) + 1, 2):
        if n % i == 0:
            return "NO"
    return "YES"

N = int(input())
print(is_prime(N))
```

This program works by defining a function `is_prime(n)` that checks if a number `n` is prime.

First, it checks if `n` is less than or equal to 1 or if it's an even number greater than 2. If either of these conditions are true, it returns "NO" because `n` is not a prime number.

Then, it checks if `n` is divisible by any odd number up to the square root of `n`. If `n` is divisible by any of these numbers, it returns "NO" because `n` is not a prime number.

If `n` passes both of these checks, it returns "YES" because `n` is a prime number.

Finally, the program reads an integer `N` from the input, calls `is_prime(N)`, and prints the result.
