This looks so alien! Does it work with the full set? The comment says 5, choose 4, but I guess it’s written as n, choose n-1?

[–] [email protected] 1 points 1 day ago

Yes, it should do. I do run the solutions against the live data, but sometimes tweak the solutions afterwards, so can't always guarantee them :-). I left the comment as 5 choose 4 as it felt clearer in the context of the test data.

It does still feel very alien at times, but I do love being able to think about how to adopt a more arrays-based approach to solving these problems.
