my barbaric Python solution takes ~.3sec/puzzle on my machine, passes sample tests. But it fails all 16 random tests, taking ~9.5 sec to do so. Interestingly, the stderr output reads:
((), (), (), ()) should equal ((1, 3, 4, 2), (4, 2, 1, 3), (3, 4, 2, 1), (2, 1, 3, 4))
when I plug the result into solution, my puzzle solver solves it correctly.

What might be going on here? Too sloooooow or am I missing something else? 🤔

these come with a free version, you can get more numbers with a paid subscription 😂
