 **NOTE**: Because we're dealing with some low-level language features, you might spot some easy ways to "cheat" on this lab, or this lab might seem frustratingly easy. We've given you some starter code to point you in the right direction — try to solve the lab as intended! You can then compare your solution with ours (found in the `solution` branch of this repository).
