Advent of Code 2021

These are my solutions written in Kotlin for Advent of Code 2021.

I am using these challenges mainly to learn and get comfortable with Kotlin 😄. I won't push solutions until the day after.

Solutions

Since each solution is an entire Gradle submodule, here are quick links to each file:

Day	Source code	Visualisation	Input
Day 01: Sonar Sweep	Day01.kt	-	input.txt
Day 02: Dive!	Day02.kt	-	input.txt
Day 03: Binary Diagnostic	Day03.kt	-	input.txt
Day 04: Giant Squid	Day04.kt	-	input.txt
Day 05: Hydrothermal Venture	Day05.kt	-	input.txt
Day 06: Lanternfish	Day06.kt	-	input.txt
Day 07: The Treachery of Whales	Day07.kt	-	input.txt
Day 08: Seven Segment Search	Day08.kt	-	input.txt
Day 09: Smoke Basin	Day09.kt	-	input.txt
Day 10: Syntax Scoring	Day10.kt	-	input.txt
Day 11: Dumbo Octopus	Day11.kt	Day11Visualisation.kt	input.txt
Day 12: Passage Pathing	Day12.kt	-	input.txt
Day 13: Transparent Origami	Day13.kt	-	input.txt

Building and testing

To clone the repository:

$ git clone https://github.com/LMBishop/advent-of-code-2021/
$ cd advent-of-code-2021

Using the helper script

The helper script will build and run the jar for the specified day code. The working directory will be work/, the input file will be copied from the day code.

Running normal solutions

$ cd work
$ ./build.sh <day code (e.g. 01, 02, ..., 25)>

Running visualisations

(Only some solutions have visualisations.)

$ cd work
$ ./build.sh <day code (e.g. 01, 02, ..., 25)> v

Using Gradle directly

Running normal solutions

Linux / macOS:

$ ./gradlew build

Specific submodule:

$ ./gradlew <submodule>:build

Windows:

gradlew build

Running visualisations

Linux / macOS:

$ ./gradlew build -Pvisualisation=true

Windows:

gradlew build -Pvisualisation=true

All output jars will be in build/ of the respective submodules.
