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)

    Well, then we have the same solution but coded very differently. Here’s mine.

    ruleApplied is one function with almost all logic. I take a range and compare it to a rule’s source range (50 98 2 is a rule). Overlaps get transformed and collected into the first sequence and everything that left goes in the second. I need two seqs there, for transformed values to skip next rules in the same map.

    Repeat for each rule and each map (seq[Rule]). And presto, it’s working!

      Yeah, roughly the same idea. I guess I could have just used HSlice for my range type, I thought maybe there was some special magic to it.

      It looks like your if-else ladder misses a corner case, where one range only intersects with the first or last element of the other. Switching to <= and >= for those should take care of it though.
