Thanks to your solution I learned more about how to use
reduce:DMy solution did work for the example input but not for the actual one. When I went here and saw this tiny code block and you saying
I was quite taken aback. And it's so much better performance-wise too :D (well, until part 2 comes along in my case. Whatever this black magic is you used there is too high for my fried brain atm)
Haha, sorry about that, it does seem quite smug :-) I went into it expecting it to be a nightmare of boxes and dimensions, but finding it something I could deal with was a massive relief. Of course once I had a working solution I reversed it back into a multi-dimensional nightmare. That's where the performance gains came from: about 10x speedup from letting Uiua build up as many dimensions as it needed before doing a final deshaping.
I enjoyed reading a different approach to this, and thanks for reminding me that
โ$"__"exists, that's a great idiom to have up your sleeve.Let me know if there's any bits of my solution that you'd like me to talk you through.
No worries, it does seem a lot less difficult in hindsight now, my mind just blanked at what I expected to be a lot more code :))
That performance improvement is amazing, I'll definitely take a look at how that works in detail later. Just gotta recover from the mental stretch gymnastics trying to remember the state of the stack at different code positions
