Building up skills with Advent of Code

I am spending this December working on the Advent of Code 2019 daily challenges. I will be using these fun programming questions to build up my C++ / Rust skills. If I run into harder questions, I may fall back on my stronger Python coding skills. My hope is that I can build better quantitative thinking with this endeavor.

Anyone interested in trying this on their part can check out (https://adventofcode.com/).
