I'm participating to the 2020 edition of Advent of Code, a nice little puzzle game for developers. It consists in solving a couple of Christmas-related programming puzzles, and it doesn't matter what language you're choosing as long as you get the solution. I warmly suggest to give it a try yourself!
To get the input for the puzzles, you'll have to log in to the site above and get your own source. I'll add an input.txt file in each directory with a sample input to work with. If you're getting the input in a browser window from the game's site, you can open your developer tools of choice and set
let input = document.body.textContent;Be warned, though, that not every solution can be executed on the browser's console, as some are meant to be run on node.js.
Here are the repositories for the solutions of the previous editions:
I'm publishing my solutions online, each in their own day-## directory, which will also contain the texts of the puzzles. The solutions are merely meant to be a reference for comparison, to see the tricks I'm using and, eventually, to discuss about improvements and new ideas.
So, if you still haven't found the solution and wish to do it on your own, this is the due SPOILER ALERT.
