 // When performing operations on elements within a collection, iterators are
 // essential. This module helps you get familiar with the structure of using an
 // iterator and how to go through elements within an iterable collection.

-// Make me compile by filling in the `???`s

-// Execute `rustlings hint iterators1` or use the `hint` watch subcommand for a
-// hint.
