    Advent of Code (by michaeljgallagher)

    It was fun figuring out the logic for decoding the numbers. Sets were pretty handy

    My solutions to Advent of Code 2021. (by ritobanrc)

    Rust -- part 1 was fairly easy, but I had absolutely no clue how to do part 2 for a long time. I ended up just brute forcing it, trying every single possible wire re-arrangement (thanks itertools::permutations). I used a bitmask to represent which lights were on (no idea if its necessary), but it was a fun exercise trying to get the bit fiddling right -- I was pleasantly surprised when it just worked (ig that's the benefit of writing small, fairly self-contained routines). My initial answer for part 2 was also reversed (3535 instead of 5353), which is why there's a rev in there near the end. Overall, very fun challenge -- I enjoyed not knowing how to approach it initially, and I'm sure lots of people will have far more clever solutions.

    Advent of Code challenge solutions (by flwyd)

    Raku, 9341 / 11194. Linked code derives segment properties from a list of digits; the original code for submission hard-coded segment-count-to-presence and segment-count-to-absence values, which was shorter but less elegant. Part 1 is a 1-liner after parsing: [+] ($_.grep(so *.chars == any(2,3,4,7)).elems for $.parsed.made)

    Discontinued Advent of Code solutions (by sjmulder)

    Interesting though that we ended up with a very similar approach from different angles - it seems like you thought about the problem and came up with how to identify the digits based on segments, whereas I chose to look at the data detached from any meaning and found that intersection counts yielded a unique sorting key - but that's in fact the very same thing.

    My Advent of Code answers (by tcsullivan)

    Clojure (GitHub). For part 2, I did process of elimination to decode the remaining digits based on the already solved digits. For example, the segments for 2 can be determined by subtracting the segments for 7 from the 5-segment digits (2, 3, 5); 2 will be the only digit with three segments remaining.

  129. Advent-Of-Code

    I think today was very difficult because of the way the problem was layed out. Most of what you need to do for part2 was explained in part1 for no reason and the example werent exhaustive. I tried doing it with sets, then I also tried bruteforcing it and in the end I ended up doing a more manual approach which is very ugly but I am too tired to refactor rigth now.

    Solutions for Advent of Code 2021 in F#

    Here's my solution in F# in Juptyer Notebook. For Part 2, used a process of elimination for mapping the other patterns. The Seq.except method became very useful.

    And part2 is here. Executes in about 40ms on my machine.

    https://github.com/alokmenghrajani/adventofcode2021/blob/main/day08/day08_gophersat.go if you want to see how to solve today's with a SAT solver. IMHO, it's cleaner with z3 but the two versions are quite similar.

    Did part 2 in Z3. It's a pretty inefficient solution, but it does work.

    Rust Each segment has a unique combination of the number of times it appears, and the set of segment counts in the digits it appears in. Using this information I make a decoder without having to hard code an algorithm. https://github.com/Crazytieguy/advent-2021/blob/master/src/bin/day8/main.rs

    Golang solutions to advent of code 2021 (by Stefansfrank)

    My code is NOT optimized for brevity but for a balance of execution speed and readability. As this is not a brute force solution, speed does not really matter - otherwise the manual statements mentioned in the beginning are most likely faster than my fingerprint comparison. It runs on my MacBook in 1.5 ms if I suppress the repeated text output that is in the Github version (3 ms with all the text output).

    Python 3.8 solution damn it took me 3 days to complete the part 2 for stupid attention error. Figuring out that counting letters in the sequence diagram was a huuuuge leap forward. Also sorting the letters.
