A tester writes a script that checks for any open ports above 3000. When those ports are found, the script should launch an additional scanning routine. When those ports are not found, the script should stop checking. Which structure is best for handling these outcomes?
A structure that calls itself for each condition
A branching approach with a fallback
A single line that halts processing after the port check
A branching approach with a fallback ensures the script tests a condition and then splits its flow accordingly. A repeated iteration would continue checking all ports unnecessarily. A structure that calls itself may lead to repetitive or recursive events outside the desired outcome. Halting processing after the first test prevents further checks where they might be needed.
