The thing that finally got businesses to finally get off IE wasn't from the browser being worse than every other option. Heck, it wasn't even because it was a decrepit piece of software that lost it's former market dominance (and if anything businesses see that as a positive, not a negative).

What finally did that was microsoft saying there won't be any security updates. That's what finally got them off their ass; subtly threatening them with data breaches, exploits, etc. if they continue to use it. I don't see google doing this anytime soon, at least not without a "sequel" like microsoft had with edge.

Surprised TOEM isn't on your list, given the premise is pretty much exactly what you describe. Last I checked it comes up on the first page or something if you sort steam by highest rated.

Lunacid might also be a good game. I think it fits your criteria for me, but that might just be for me.

I dunno, having two primes sum to a power of two is undeniably powerful in my experience. The number of times a calculation goes from tedious to trivial from this sum is incalculable. The lowest I'd put it is A.

Darn that sucks to hear. I was somewhat active several months ago. Unfortunately the server never hit "critical mass". My interest in any given game also waxes & wanes significantly so I know I kinda abruptly stopped playing.

~~Isn't the Weierstrass function a counterexample to the premise?~~ Wait no, I misread. It's the converse.

I have mine set up with a bunch of categories that are sorted with a prepended 3-digit number. Allows me to have different sections of category without it getting mixed up. ex:

010 S
011 A+
012 A
013 A-
014 B+
etc...
350 plz play soon
355 wont play
...
800 dont remember buying this

When I read the problem description I expected the input to also be 2 digit numbers. When I looked at it I just had to say "huh."

Second part I think you definitely have to do in reverse (edit: if you are doing a linear search for the answer), as that allows you to nope out as soon as you find a match, whereas with doing it forward you have to keep checking just in case.

Oh yeah, I misspoke, gonna edit.

hmm, my code keeps getting truncated at for y in .., anyone have any idea why? Maybe the "<" right after that confuses a parser somewhere?

Did this in Odin

Here's a tip: if you are using a language / standard library that doesn't have a set, you can mimic it with a map from your key to a nullary (in this case an empty struct)
