Finally managed to finish Day 22. Had to learn some new material to do it myself. It was quite an interesting experience. Some spoilers in the thread. https://github.com/Rtchaik/AoC2019/blob/master/src/advent2019/day22/solution22.kt

Actually, almost everything on this day is related to operations with modulo. And the main problem was that division works differently to other operations. It took me a while to understand this, google and learn this topic.

Nice work! I'm so lost on Part 2 and this is so nice and clean.

One small thing that might make things nicer to look at, Java defines BigInteger.ZERO and BigInteger.ONE.

Great! Thanks.
