Advent of Code provides some interesting little programming exercises every day between now and December 25th. Today’s took me only a couple of minutes (and naturally I did them in OCaml.)
I’ve set up a private leaderboard for interested people, use code 215585-9abd1c2a to join it.
In case it dispels any confusion: I found that I could only view the private leaderboard entry field if I was logged in first before trying to visit that URL. Otherwise it redirects to the general leaderboard.
