Advent of Code 2023 solutions

A set of 25 puzzle inputs and 50 puzzle solutions, two for each day. Most can be solved in minutes. The puzzles can be found here, although only the first one for each day is visible until you solve it.

Most solutions output at most two lines, the answers to part 1 and 2; but some provide more information in the form of e.g. graphics.

Run a solution by passing the puzzle input to the program:

./two.awk < input2

or

./five.py -v < test5

or

kotlinc -include-runtime -d seven.jar seven.kt && java -jar seven.jar < input7

or

./sechszehn.py -vv <input16

or

./xmaseve.py -v 7 27 <test24
