Advent of Code 2024

Solutions for the 2024 Advent of Code

Building

This project makes use of Go 1.23.3.

git clone [email protected]:heldeen/aoc2024.git
go test ./...
go build

Running the Solutions

To run a solution, use the problem name followed by the path to an input file.

For example, to run problem 2 a:

$ go run ./main.go 2 a -i ./challenge/day2/input.txt
Day 2, Part A - Answer: 9633
Took 999.4µs

NOTE: Input file is optional and, if omitted, it's location will be inferred by the day parameter to be a file named input.txt located in the challenge/dayX/ folder.

Adding New Solutions

A generator program is included

$ go run ./main.go gen 7
Took 501.833991ms

This executes the logic in gen/problem.go that makes templates for each day. For example, go run main.go gen 9 will generate the following files:

• cmd/importDay9.go: A "glue" file combining commands for both of the day's problems to simplify wiring up subcommands
• challenge/day9/a.go: The main problem implementation stubbed out for Part A: func A(*challenge.Input) int
• challenge/day9/a_test.go: A basic test template for Part A
  • This contains a const sample that is meant to get the sample input from the AoC website problem description. It uses that to feed the solution input for testing.
• challenge/day9/b.go: The main problem implementation stubbed out for Part B: func B(*challenge.Input) int
• challenge/day9/b_test.go: A basic test template
  • This references the sample constant in the same day's a_test.go for testing the Part B solution.
• challenge/day9/input.txt: The challenge input downloaded from the AoC website. Grab your https://www.adventofcode.com session cookie value and store it in ~/.tokenfile to enable this.
• .idea/runtimeConfigurations/TestA_in_aoc2022_challenge_day9.xml: The JetBrains Goland configuration for running the tests in a_test.go.
• .idea/runtimeConfigurations/TestB_in_aoc2022_challenge_day9.xml: The JetBrains Goland configuration for running the tests in b_test.go.
• .idea/runtimeConfigurations/Run_aoc2022_challenge_day9_partA.xml.xml: The JetBrains Goland configuration for running the solution in a.go against the input.
• .idea/runtimeConfigurations/Run_aoc2022_challenge_day9_partB.xml.xml: The JetBrains Goland configuration for running the solution in b.go against the input.
