Advent of code

Advent of code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. People use them as interview prep, company training, university coursework, practice problems, a speed contest, or to challenge each other.

Conventions

Why I don't include input files:

AoC creator asked to not share input files (in this tweet and in the subreddit wiki), so I do not include them into my repo.

You can still run every challenge with your input, available at Advent of code, after login (input is unique for every user).

Content of the repo:

• <year>/day<day>/day<day>.*: clean and refactored solution
• <year>/day<day>/day<day>_part*_original.*: solution written as fast as possible (impossible to read and almost always inefficient)
• <year>/day<day>/day<day>_bruteforce.*: bruteforce or other approaches to test efficiency
