Advent of Code 2021

This repo is for the annual Advent of Code programming challenge, 2021 version.

This year, I wanted to brush up on C++ and Java, so on certain days when I had more time I decided to use them instead of my main language (Python). This resulted in a disgusting file structure with multiple build systems. My C++ compilation broke on day 5 when I tried to include the Boost package, so I stopped using it temporarily.

Nevertheless, I plan on actually completing AoC for the first time ever and I'm expecting to gain a lot of needed familiarity with C++ and Java.

Personal Highlights: Day 12: My first time using BFS in Python. Definitely worth reviewing before an interview

Day 15: My first time using Dijkstra in Python, and the Dijkstar library

Day 16: had me stuck for a week. Decided to implement the logic into one file instead of two like I originally tried

Day 23: realizing I could use game state positions as nodes on a graph

Day 24: using Streamlit to make a dashboard to easily test hypotheses with the model number validator
