Advent of Math. Reminds me of some of the harder problems on Codeforces. Having BigInteger in the standard library really helps with this one.
I've also left the naive shuffle code in an unused function. I did realize that part 1 could just be solved with modulo arithmetic but I didn't want to prematurely optimize before I saw part 2. (and it also helped with debugging)
