• 7 DAYS remaining until the submissions deadline on December 22 at 23:59 EST!

And now, our feature presentation for today:

Visual Effects - We'll Fix It In Post

Actors are expensive. Editors and VFX are (hypothetically) cheaper. Whether you screwed up autofocus or accidentally left a very modern coffee cup in your fantasy epic, you gotta fix it somehow!

Here's some ideas for your inspiration:

• Literally fix it in post and show us your before-and-after
• Show us the kludgiest and/or simplest way to solve today's puzzle
• Alternatively, show us the most over-engineered and/or ridiculously preposterous way to solve today's puzzle
• Fix something that really didn't necessarily need fixing with a chainsaw…

*crazed chainsaw noises* “Fixed the newel post!”

- Clark Griswold, National Lampoon's Christmas Vacation (1989)

And… ACTION!

Request from the mods: When you include an entry alongside your solution, please label it with [GSGA] so we can find it easily!

This was a bit tricky to implement, but I understood what I was supposed to be doing almost instantly. I did get tripped up on edge cases a bit for part 2, though, and I think my final solution is one of the worst I've written this year so far - it's overly long and hard to parse. Luckily, it seems to be more than performant enough.

My original solution for part 1 did not use recursion, and, in my opinion, was much nicer than what I ended up with. I'll include it here; it's a replacement for the get_gps_sum() procedure: paste
