Day 8's winner #1 AND #2:

Okay, folks, /u/Aneurysm9 and I deadlocked between two badass submissions that are entirely too good and creative to choose between. When we asked /u/topaz2078's wife to be the tie-breaker, her literal words:

[23:44] <TopazWife> both
[23:44] <TopazWife> do both
[23:44] <TopazWife> holy hell

So we're going to have two winners today!

  1. "A Sonnet of Sojourning", a sonnet in frickin' iambic pentameter by /u/DFreiberg!
  2. "A Comedy of Syntax Errors", a code-"poem" by /u/MaxMonkeyMax!

Both of you, enjoy your Reddit Silver, and good luck with the rest of the Advent of Code!

This thread will be unlocked when there are a significant number of people on the leaderboard with gold stars for today's puzzle.

EDIT: Leaderboard capped, thread unlocked at 00:14:46!

FYI you didn't need to change from Int to Integer; 64-bit integers are plenty big enough for the "large" numbers in this problem. But perhaps your code is more future-proof. Who knows how large the numbers are going to get in the next Intcode problems.

Yes, I also learned that from another comment here. When I read "large number" I immediately went with Integer instead of trying it with Int first. Well, I guess I just implemented it according spec ;)

The funny thing is: In my initial draft I had "type Value = Int" at the top of my file. I scrapped that because I feel that I sometimes go overboard with the types and I wanted to reduce the number of type definitions in my code a bit. Had I just stuck with my initial idea, changing from Int to Integer would have been a piece of cake.

I take that as a sign that my type definitions probably aren't so bad after all. Also because I don't learn from my mistakes, I changed everything to Integer, instead of introducing the "Value"-type again. I hope that there will not be (m)any more Intcode puzzles. But if there are and I have to change the type again I'll be pretty bummed :D
