Amazing! Thanks for sharing.

The farthest I got in the ICPC was regionals. I was tasked to make the team binder. I was a budding LaTeX enthusiast then but our coach wanted me to do it in...MS Word. Not that he didn't know LaTeX either (he's a published math/CS researcher after all), it's just the cultural ubiquity and comfort of MS Word. :(

The result was something more like https://github.com/ludopulles/tcr/blob/master/TCR-Sudo.pdf . I love how information-dense tcr.pdf looks in comparison. They even have a table of contents!
