Advent of code 2024

My solutions to some advent of code 2024 problems. This year most solutions are all written in GO, a high level procedural programming language.

My consistency and correctness has improved dramatically compared to my previous experience. By christmas day 2024, I completed the following days. (a refers to part one, b refers to part 2)

• 1a
• 2a, 2b
• 3a, 3b,
• 6a
• 7a, 7b
• 9a
• 11a
• 14a, 14b
• 15a
• 17a
• 18a
• 22a
• 24a
• 25a

Boxing day boom

After the event ended, I returned to some projects to improve and experiment with my solutions.

• day_11
  • day_11/main.go completed a go implementation
  • day_11/day_11_c2 completed an array-backed dictionary implementation in C
  • day_11/day_11_rust rewrote solution in rust to compare performace to go and C
  • day_11/day_11_custom_hash implemented an experimental datastructure solution in C
  • day_11/day_11_cpp ported C solution to C++ to use a professional hashmap implementation

Better late than never

With more experience behind me, I decided in mid 2025 to review the unsolved problems and made some progress.

• day_1/c/main.c repeated day one, part one this time in the C programming language. use make to run it.
• day_23a/cpp/main.cpp solved the graph nodes connection problem in C++. use make to run it

Try it out

Each day has its corresponding day_ folder. Eg day_1. I do not condone cheating, Do not use my code to solve the puzzles for you. However, if you have completed your own solution and would like to compare approaches:

1. Open a terminal
2. Clone this repository
3. Install the go compiler
4. Open a day_ folder such as day_1
5. Supply the puzzle input or example as input.txt inside the folder
6. Use go run . to compile run the main.go file
