Day 7: Camel Cards

Megathread guidelines

Keep top level comments as only solutions, if you want to say something other than a solution put it in a new post. (replies to comments can be whatever)
Code block support is not fully rolled out yet but likely will be in the middle of the event. Try to share solutions as both code blocks and using something such as https://topaz.github.io/paste/ , pastebin, or github (code blocks to future proof it for when 0.19 comes out and since code blocks currently function in some apps and some instances as well if they are running a 0.19 beta)

It's Uiua time!

It works, but even I can't understand this code any more as I'm well into my second beer, so don't put this into production, okay? (Run it here if you dare.)

How do you debug this language??

[–] mykl 1 points 11 months ago

Lots and lots of print statements :-)
