• Interpreter pattern?

Question related to mission Hacker Language


So in the description it said "In this mission you could use the Interpreter design pattern."

I've looked that up a little but I still don't see how to use it in this task.

I can build a working HackerLanguage() class without using the pattern, but I still want to know how to use it here and solve this task with it, instead of looking up other people's answers and learn it afterwards.

Can somebody give me some hints?

Thank you.
