Learning Odin through Advent of Code 2025
You need to have an odin compiler installed to build this project. For instructions see odin getting started
Inside the project directory run
> odin build .
This should cause an executable file called advent-of-code-2025 to appear in the project directory (yours might have a different name if you renamed the project directory)
Program picks which puzzle to run based on command line argument so running
> advent-of-code-2025 day_1
will print the solutions to both parts of the first day's puzzle. Similarly providing (day_2/day_3/etc.) as the argument will run puzzle from that day
> ./advent-of-code-2025 day_1
part 1: 1007
part 2: 5820
