Day 12: Hot Springs

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)

    Thanks for the detailed explanation. It helped a lot, especially what the tbl actually holds.

    I’ve read your code again and I get how it works, but it still feels kinda strange that we are considering values outside of range of a and b, and that we are marking them as correct. Like in first row of the example ???.### 1,1,3, there is no spring at 8 and no group at 3 but we are marking (8,3) and (7,3) as correct. In my mind, first position that should be marked as correct is 4,2, because that’s where group of 3 can fit.

      If you make the recurrent case a little more complicated, you can sidestep the weird base cases, but I like reducing the endpoints down to things like this that are easily implementable, even if they sound a little weird at first.
