22-2 commentaryI got a different solution than the one given on the site for the example data, the sequence starting with 2 did not yield the expected solution pattern at all, and the one I actually got gave more bananas anyway.

The algorithm gave the correct result for the actual puzzle data though, so I'm leaving it well alone.

Also the problem had a strong map/reduce vibe so I started out with the sequence generation and subsequent transformations parallelized already from pt1, but ultimately it wasn't that intensive a problem.

Toddler's sick (but getting better!) so I've been falling behind, oh well. Doubt I'll be doing 24 & 25 on their release days either as the off-days and festivities start kicking in.
