/*
Design a simple object-oriented system to manage basic information about airports. Your system should support the following functionalities:
Add a new airport to the system, including airport code, city, and country.
Display information about a specific airport based on its code.
Allow users to search for airports by --city or country-- and display a list of matching airports.
Allow airports to update their information, such as city or country, if needed.
Remove an airport from the system.
Your implementation should use appropriate classes and methods to represent airports and the airport system
