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)

I tried to do this one as quickly as possible, so the code is more messy than I would prefer, but it works, and I don’t think the solution is too bad overall.
Edit: I went back and changed it to be a bit better. Here are my new solutions:
