My attempt at AoC in C++ (disclaimer: I am a Data Scientist so C++ was stretching it for me. I am using this as an opportunity to understand how lower-level stuff work and help other Data Scientist fellows learn Computer Science & algorithms).
2021 was a very fun adventure and I got to get my hands dirty (I really enjoy coding and problem solving).
I tried to solve most problems with a good solution. In some instances, I challenged myself to write high performance code and these solutions are suffixed with _opti.
The code start with main.cpp. Change the #include to the day you are interested in running.
I hope you enjoy it as much as I did.
