Dang, I missed seeing this before the solution was posted. And oh dear, it’s high-complexity. Oh well, I’ll give it a shot anyway!
Edit: Hah, I spent an hour checking one thing (which went nowhere), and then ran out of steam, and now I can no longer resist checking the answer. So much for that 😅 Next time I’ll try to check my notifications more often so I see the next one before the answer is up, maybe that’ll give me more drive to keep at it.
