Solutions to Advent of Code 2025 tasks in the Rust language.
Solutions return answers to two parts of the task at once.
The purpose of these solutions was to write algorithms that solve 2 parts of the task at once (at the same time, if possible), without using third-party crates and with as few formatted lines of code as possible, with a balance for optimization. Of course, you can increase the code of each algorithm by 2-3 times and get the most optimized code in both time and memory. But that wasn't my main goal.
