-// box1.rs
-//
-// At compile time, Rust needs to know how much space a type takes up. This
-// becomes problematic for recursive types, where a value can have as part of
-// itself another value of the same type. To get around the issue, we can use a
-// `Box` - a smart pointer used to store data on the heap, which also allows us
-// to wrap a recursive type.
-//
-// The recursive type we're implementing in this exercise is the `cons list` - a
-// data structure frequently found in functional programming languages. Each
-// item in a cons list contains two elements: the value of the current item and
-// the next item. The last item is a value called `Nil`.
-//
-// Step 1: use a `Box` in the enum definition to make the code compile
-// Step 2: create both empty and non-empty cons lists by replacing `todo!()`
-//
-// Note: the tests should not be changed
-//
-// Execute `rustlings hint box1` or use the `hint` watch subcommand for a hint.
