Advent of Code 2018

This repository contains my solutions to Advent of Code 2018. After three years solving the problems exclusively in Scala, I decided to solve each day of 2018 in a different programming language.

Rules

Some "rules" I set up for myself before starting solving the problems:

• The languages to be used in each day are the following, in order: Idris, Prolog, Lua, Rust, C++, Ruby, Octave, Python, Erlang, R, OCaml, Dart, PHP, Elixir, Pony, Scala, Swift, Haskell, Go, Nim, Kotlin, TypeScript, Perl, Java and Clojure.
• The solutions should read the input from a predefined file (named <day>.input) and write the solution to the standard output.
• The solutions should take less than a minute to output the correct answer on my machine.
• Dependencies should be limited to each language's standard library.

Problems

• Day 1: Chronal Calibration (Idris): problem statement / solution
• Day 2: Inventory Management System (Prolog): problem statement / solution
• Day 3: No Matter How You Slice It (Lua): problem statement / solution
• Day 4: Repose Record (Rust): problem statement / solution
• Day 5: Alchemical Reduction (C++): problem statement / solution
• Day 6: Chronal Coordinates (Ruby): problem statement / solution
• Day 7: The Sum of Its Parts (Octave): problem statement / solution
• Day 8: Memory Maneuver (Python): problem statement / solution
• Day 9: Marble Mania (Erlang): problem statement / solution
• Day 10: The Stars Align (R): problem statement / solution
• Day 11: Chronal Charge (OCaml): problem statement / solution
• Day 12: Subterranean Sustainability (Dart): problem statement / solution
• Day 13: Mine Cart Madness (PHP): problem statement / solution
• Day 14: Chocolate Charts (Elixir): problem statement / solution
• Day 15: Beverage Bandits (Pony): problem statement / solution
• Day 16: Chronal Classification (Scala): problem statement / solution
• Day 17: Reservoir Research (Swift): problem statement / solution
• Day 18: Settlers of The North Pole (Haskell): problem statement / solution
• Day 19: Go With The Flow (Go): problem statement / solution
• Day 20: A Regular Map (Nim): problem statement / solution
• Day 21: Chronal Conversion (Kotlin): problem statement / solution
• Day 22: Mode Maze (TypeScript): problem statement / solution
• Day 23: Experimental Emergency Teleportation (Perl): problem statement / solution
• Day 24: Immune System Simulator 20XX (Java): problem statement / solution
• Day 25: Four-Dimensional Adventure (Clojure): problem statement / solution

Running

You can run a solution by typing the following, replacing <X> with the day of the desired problem:

$ ./run.sh <X>

You might need to install some dependencies. It should be easy to guess which ones by looking at the run.sh script.
