Advent of Code

Advent of Code 2021

Here are some solutions (or attempted solutions) to the 2021 Advent of Code puzzles.

Scripts in each day directory can be run via:

$ ./1.py < input.txt

# Or, for shell scripts
$ ./1.sh < input.txt

Use 2 instead of 1 for the second puzzle of the day.

The example input (as given in the puzzle description) for each day is in test.txt.

The input I had to solve for is in input.txt.

Our private leaderboard is here. Let me know if you want to join it.
