DeepSeek V4 Flash

Write a Python function to check if a number is prime and explain the logic.

def is_prime(n):
    if n <= 1:
        return False
    for i in range(2, int(n ** 0.5) + 1):
        if n % i == 0:
            return False
    return True

# This function checks divisibility only up to the square root of n,
# which improves efficiency.

Given a list of files in a directory, write a plan to find and delete all files older than 30 days.

1. List all files with their last-modified timestamps.
2. Compute the cutoff date (today - 30 days).
3. Filter files whose modified time is before the cutoff.
4. Confirm the filtered list, then delete each file.
5. Log the deleted file names for auditing.
