-In the rest of the steps in this project you will find tasks to implement something with the collections,
-in the **Hints** section you will find the built-in functions that can do it. Let's try to find the necessary functions in the official documentation and only then check your guess with the hints.
-The ability to search for something in the documentation is also a very important skill for programmers.
