From this puzzle I found out how annoying it was to implement queue-based algorithms like Dijkstra's, having to specify an entirely new class for the elements of the queue. One can probably do some hack by using
Object
arrays and stuff, but I would rather not do that. Perhaps I can find a more convenient way in the future.Anyhow, this puzzle was fairly fun (I love graph-based puzzles) and I am happy with my solution (and that my solution runs in about 250 microseconds each for part 1 and part 2).
