Advent of Code 2021
Solutions to the 2021 Advent of Code.
* means that a given day has a visualisation
| Day | Status | Solutions | Notes |
|---|---|---|---|
| 01 - Sonar Sweep | ★ ★ | Python, Go, Nim | Numbers and sliding windows. |
| 02 - Dive! | ★ ★ | Python, Go | Have this set of instructions and do something sensible with it. |
| 03 - Binary Diagnostic | ★ ★ | Python, Nim | Bit twiddling aplenty! |
| 04 - Giant Squid | ★ ★ | Python | B-I-N-G-O, B-I-N-G-O, B-I-N-G-O and Bingo was his name-o! |
| 05 - Hydrothermal Venture | ★ ★ | Python, Go, Nim | Pointy. |
| 06 - Lanternfish | ★ ★ | Python | At this rate, the mass of the fish would surpass that of the Earth pretty quickly. |
| 07 - The Treachery of Whales | ★ ★ | Python | I'm not 100% sure my solution for part two is valid for all possible inputs. |
| 08 - Seven Segment Search | ★ ★ | Python, Go | I may have taken the easy way out for part two, but it does work! No-one ever said the smart solution is the best solution, anyway. |
| 09 - Smoke Basin * | ★ ★ | Python | Schmokey! Also, as it turns out, I struggle to implement basic logic. Fun. |
| 10 - Syntax Scoring | ★ ★ | Python | I can't say I've ever broken something so thoroughly that it has a syntax error on every line... |
| 11 - Dumbo Octopus | ★ ★ | Python, Nim | Cellular automata my beloved <3 |
| 12 - Passage Pathing | ★ ★ | Go | I couldn't tell you how it works, but it does kinda work and I think I have a vague idea (external help was used). |
| 13 - Transparent Origami | ★ ★ | Python, Nim | I got stuck for hours on an intermittent off-by-one error. :( |
| 14 - Extended Polymerization | ★ ★ | Python | Another off-by-one error, but this time it was because of dodgy division. Wonderful. |
| 15 - Chiton | ★ ★ | Python | Pathfinding is hard |
| 16 - Packet Decoder | ★ ★ | Python | Parsing and interpreting stuff is surprisingly enjoyable |
| 17 - Trick Shot | Unattempted | ||
| 18 - Snailfish | Could not solve | ||
| 19 - Beacon Scanner | Unattempted | ||
| 20 - Trench Map * | ★ ★ | Python, Nim | Took a moment to realise that the infinite grid alternates between lit and unlit, and even then I had to look at someone else's solution to realise it. |
| 21 - Dirac Dice | ★ ☆ | Python | Couldn't be bothered with part two - I've got too much going on at the moment to spend a lot of time thinking about it. |
