Welcome to the design patterns module! This challenge will serve as the first tutorial to how you will mainly be
completing the challenges in this specific module. "Start" this challenge, and then you can interact with it
by clicking on "Workspace" in the site's navigation bar or "VSCode Workspace" in the pop-up after the
challenge has successfully started.
Start by running the checker Python executable by doing the following in the terminal:
$ cd /challenge
$ ./checker
The executable will then give you further instructions.
NOTE: For a Python file, you would usually run it by doing $ python3 [filename]. For this environment and platform,
due to how permissions are handled so that you cannot simply read the flag, you MUST run checker by
doing $ ./checker so that it can successfully read the flag and print it in the terminal. If you complete the tasks
for the challenges but use $ python3 checker, you will get an error in the terminal (the file won't actually be
executed).
In addition, you will get an error if you try to read the checker file / open it up in VSCode. This is intentional. Again, you MUST run checker as specified above.
