Needed a small nudge for part 2. It was obvious we needed to look for cycles (the hints in the text were strong, and we have a few of these every year unfortunately), but it didn't occur to me to look the dimensions independently. The code is OK but nothing special.

The `.sign` function is a perfect example of the thought that went into the standard library.
