I dont have any idea how to do this in C or Python. It came today in a Hackerank test.

What experience do you have in coding?

Basic level coding in C and Python 3

A side note: wouldn’t it be a bit better to start with easy tasks, and then move on to such tests?
I’ve been solving some of the tasks, and while they might look easy to me, I think they are nice introduction to Python.

You would probably need to create some sort of database-like structure for the task above, along with command parser (there are some ready solutions available, but not sure if they can be used in this task - shouldn’t be hard to do it on your own tho).
