Not much to say here just go to the AdventOfCode 2019 Website and check out the puzzles. There is a new one each day that you have to solve with programming and get points.
I choose to use Rust. Not because it's my favorite language (I have none), or that it is very difficult or anything challanging in general, but it's a language I want to learn for a long time, and finally found a reason to do so.
First run cargo update to install the dependencies.
After installing the dependencies you can simply run cargo run --bin dayXX (Replacing XX with a number from 1-25).
You can also just build the binary with cargo build --bin dayXX, the built binary is stored in target/debug/dayXX
The debug binaries are a bit slow sometimes. You can add --release to build/run the optimized version. If you build a release binary it will be stored in target/release/dayXX.
On systems that support the bash syntax (Linux, MacOS, Linux System for Windows, git bash, ...) you can also run the run_all_days.sh shell script. The script will build all days (with the release target) and run them.
The solutions here are implemented me, they might not be the best solution possible.
If I get stuck on a puzzle I will look in other solutions, but I will still implement them myself after I understood the concept.
After I implemented my version I will also try and optimize it even with inspiration from other solution, but the same rule applies: I will implement it myself when I can understand, how and why that optimization works, otherwise I won't use it.
I will also mark solutions / optimizations inspired by other ideas.
