// Get a slice out of Array a where the ??? is so that the `if` statement
// returns true. Scroll down for hints!!
fn main() {
let a = [1, 2, 3, 4, 5];
let nice_slice = ???
if nice_slice == [2, 3, 4] {

// Take a look at the Primitive Types -> Slices section of the book:
// http://doc.rust-lang.org/stable/book/primitive-types.html#slices
// and use the starting and ending indices of the items in the Array
// that you want to end up in the slice.
// If you're curious why the right hand of the `==` comparison does not
// have an ampersand for a reference since the left hand side is a
// reference, take a look at the Deref coercions chapter:
// http://doc.rust-lang.org/stable/book/deref-coercions.html
