// iterators1.rs

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

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