❄️ Repo for my solutions to Advent of Code 2020
-
Day 1: Interesting first day! Site went down, so was unable to retrieve my input. Site was back up in about 3 minutes, and I had already written my code, so it was just a matter of copy pasting. Got place 370 on first part and 167 on part two, globally.
-
Day 2: Today's problems were a little bit tougher than yesterdays, but not terribly bad. I unfortunately turned in a couple of wrong answers which meant I had to wait to be able to submit my correct answer. Took me 14 minutes to get both stars.
-
Day 3: A good day today! Kinda interesting and made a quite simple algorithm.
-
Day 4: Today's problem was a bit tricky. Involved a bit of nasty if statements from my part. But got there in the end!
-
Day 5: Day 5 was a fun problem! Involved some math and logic and that's always nice!
-
Day 6: This day's problem was relatively easy, however it took me a minute before understanding what to do on part 2.
-
Day 7: Interesting problem today, a bit of recursion and using dicts goes a long way!
-
Day 8: I really liked today's problem. It's fun trying to parse and run a made up programming language!
-
Day 9: My solution for today was a rather brute force method which worked surprisingly well, even if it's time complexity wasn't that good.
-
Day 10: Today's problem was a bit more difficult for me. I haven't worked that much with combinatorics, so it was good practice :)
-
Day 11: This problem was quite interesting! It took me a bit of extra time to get right since I had read the instructions too fast and missed out a case :(
-
Day 12: Interesting stuff, thought about using complex numbers to decide angle but it would be nowhere near as fast as just using basic linear algebra vector rotation.
-
Day 13: A lot of math was involved in this one, ended up using the chinese remainder theorem to solve part 2.
-
Day 14: Today was fun! I haven't had much time to do these problems in the morning unfortunately, so I've fallen down the leaderboard :(
-
Day 15: I went up in time today! I had some trouble getting the hang of the rules for the game the elves were playing, but once it clicked I managed to solve it relatively quickly.
-
Day 16: This was a really cool problem, and unlike any problem I've done before. It was super interesting to try to figure out which column that corresponded to which.
