Solutions

First ten puzzles were solved as they were published, then came the infamous Dec 11 task, which crushed my hopes and motivation.
After some desperation, I've managed to solve first 20 puzzles before Christmas, then took a long break and finished all challenges on March 19th 2017.

Comments, suggestions and critiques are welcome.

 

2023 update:

• I solved several tasks in Clojure in November 2023, as a preparation for AoC 2023.
• I also did some visualizations. See below for gifs.
