Advent Of Code 2019

It's almost December which means it's almost time for Advent of Code 2019. Advent of code is an annual computer programming competition created and ruyn by Eric Wastl. It's been running since 2015. I've written about it before, mostly from a teacher's point of view (Solve A to Solve B, Data structures and Hidden Complexity, Tools can shape how we think and a few others). Basically, Eric releases one poblem a day at midnight from Dec 1 through Dec 25.

It gets easier (or advent of code 2016 day 19)

Today's Advent of Code problem was a variant on the Josephus problem. I recalled that there was a formula to figure out the sole survivor but I decide to run a simulation rather than looking it up. I also decided to write it up in C++, well, really C with cout instead of printf. Part 1 was the traditional problem. Part 2 was a variant where at each iteration, you remove the elf opposite the elf being processed (see the problem description for details).
