My solutions for the 2021 edition of the Advent of Code, using Rust and SOM (Simple Object Machine)

Advent of Code 2021

These are my solutions for the 2021 edition of the Advent of Code.
The solutions are all implemented using both Rust and SOM (Simple Object Machine).

Day 19 Update

I found Day 19 has been significantly harder than previous days, and it has ended my run of solving each puzzle on the same day of its release.
And since Christmas is around the corner, I'll be solving these and the rest of the puzzles at a later time.
I may also revisit some of the old solutions to improve their performance (mostly for the SOM ones, since the Rust ones are already plenty fast).

How to run

Here is how you can run each of the Rust solutions:

# NOTE: You can add the '--release' flag to these commands to build with optimizations enabled.

# This will run the solution for day 1.
cargo run -- 1

# This will run the solution for day 2.
cargo run -- 2

# And so on, up to day 24 ...

Here is how you can run each of the SOM solutions using SOM-java or SOM-rs:

# using `som-java` for day 1 and day 2:
${SOM_JAVA_DIR}/som.sh -cp ${SOM_CORE_LIB_DIR}:som AoC 1
${SOM_JAVA_DIR}/som.sh -cp ${SOM_CORE_LIB_DIR}:som AoC 2

# using `som-rs` for day 1 and day 2:
som-interpreter-bc -c ${SOM_CORE_LIB_DIR} som -- AoC 1
som-interpreter-bc -c ${SOM_CORE_LIB_DIR} som -- AoC 2

You can also call each day using their class more directly, the following way:

# using `som-java` for day 1 and day 2:
${SOM_JAVA_DIR}/som.sh -cp ${SOM_CORE_LIB_DIR}:som Day01
${SOM_JAVA_DIR}/som.sh -cp ${SOM_CORE_LIB_DIR}:som Day02

# using `som-rs` for day 1 and day 2:
som-interpreter-bc -c ${SOM_CORE_LIB_DIR} som -- Day01
som-interpreter-bc -c ${SOM_CORE_LIB_DIR} som -- Day02
