// This example panics because the second time it calls `pop`, the `vec`
|
||||
// is empty, so `pop` returns `None`, and `unwrap` panics if it's called
|
||||
// on `None`. Handle this in a more graceful way than calling `unwrap`!
|

// Execute `rustlings hint option1` for hints :)

// I AM NOT DONE
