Primed for Action — Hack The Box

Description

The task provided a web interface with a code editor. The goal was to write a script that reads a list of numbers from stdin, identifies the two prime numbers in the list, and outputs their product.

Analysis

This is a classic coding challenge. We are given a list of numbers, among which we need to find exactly two prime numbers and multiply them. The main difficulty lies in correctly implementing the primality check and handling the input data.

Solution

#!/usr/bin/env python3
import sys

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