Day 5: If You Give a Seed a Fertilizer
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)

Rank 276 on part 2, personal best for me! I spent too much time struggling with parsing, the lib I’m using doesn’t have an easy way to just throw out some values, so I had to filter out the first line of sections. Part 1 was relatively straightforward once parsed though, and part 2 I knew what I had to do, I just didn’t want to. But the naïve way is… several orders of magnitude too slow.
