// This is a quiz for the following sections:

// - Strings

// Ok, here are a bunch of values-- some are `String`s, some are `&str`s. Your
|
|
// task is to call one of these two functions on each value depending on what
|
|
// you think each value is. That is, add either `string_slice` or `string`
|
|
// before the parentheses on each line. If you're right, it will compile!
|
|
|
|
// I AM NOT DONE
