+// 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.
