Day 2: Cube Conundrum

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/ or pastebin (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)

Another nim person! Have you joined the community? There are dozens of us!

Here's mine (no code blocks because kbin):

Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: [email protected]

Have you joined the community?

Yep, but it is a bit quiet in there.

Good solution. I like your parsing with scanf. The only reason I didn't use it myself - is that I found out about std/strscans literally yesterday.

I actually just learned about scanf while writing this. Only ended up using it in the one spot, since split worked well enough for the other bits. I really wanted to be able to use python-style unpacking, but in nim it only works for tuples. At least without writing macros, which I still haven't been able to wrap my head around.
