Solutions of the problems in AoC2021, using Python. Trying to focus on:

• high-performance solutions
• pure functions

Please create a new virtual environment with Python 3.7. For specific package requirements, check setup.cfg (running pip install -e . from the repo root folder should install all needed requirements).

The input data is available in the data/ folder, as data_DD.txt, where DD is the day of the problem. The scripts to compute the answer to the challenges are available in the bin/ folder.

The solution for each day contains a get_solution() function, which returns the two answers. The answers are tested for correcness and time (see test/), which enables tinkering with the code without losing the desired properties.
