In this episode, we completed day 4 of Advent of Code y2021 using Rust!

In today's challenge we needed to simulate a game of Bingo (against a giant squid 🦑) and figure out which board would win first (part I) and last (part II).

The solution wasn't particularly complicated but it was a great exercise to get to play around with few interesting concepts.

We used `filter_map` (https://doc.rust-lang.org/core/iter/trait.Iterator.html#method.filter_map) over a vector of reference as a quick way to be able to filter out the winning boards dynamically.

We also got to play a bit with iterator chaining (https://doc.rust-lang.org/std/iter/trait.Iterator.html#method.chain).

If you have any suggestion, we'd love to hear it, so please leave a comment or a create a PR!
