Advent of Code 2025

This repository contains solutions to the Advent of Code 2025.

What was in the scope

• Finding a solution to both parts of each daily puzzle.

• Sticking solely to Python with no external dependencies.

• Not reusing any code between any of the daily puzzles.

• Sticking to synchronous execution on a single thread.

• Writing correct code that is relatively nice and elegant.

• Solving each problem in a reasonable amount of time.

• Answering each part of the puzzle in a separate run.

What was out of scope

• Strictly validating the input as a whole for each puzzle.

• Providing the most performant or optimized solution.

• Making the code more readable or maintainable.

• Avoiding code duplication or sticking to a convention.

• Reducing the number of lines or characters in the code.

(If any of the above is fulfilled, it is simply by chance or by habit.)
