This question appears to be off-topic because it is a code review request. This might be better suited to the Code Review Stack Exchange site.

@Morwenn Enjoy the fame while you can. We'll all end up in oblivion.
The fame is already behind me, I'm but a ghost here
I only pop up once every few months/years to share a new fun sorting algorithm
I do keep fond memories of the time I've spent here :)
@Morwenn I get that sometimes. But I've had an additional 200k views in a couple of months and say 10/20 additional upvotes on my old answers. Kinda puts it in perspective for me.
I was surprised because my upvotes seemed to correspond to questions and answers that were mostly a few days apart

@AlexV That's a known problem that they won't fix. It means there's plenty in the queue, but you've reviewed them all already. The queue is not empty, but your queue is.
@Morwenn Famous ghost though, welcome back.
@Mast NGL that's dumb. But IMO so is also not showing the number of reviews you can do as a number.
@Mast I'm surprised that people still remember me :p

All numbers n <= 3 are prime, special case that so you can skip even divisors inside your loop. See also Checking if a number is prime in NASM Win64 Assembly/ for a more efficient prime-checking loop which checks the quotient against divisor to stop at about sqrt(n) instead of uselessly going all the way up to n-1. Porting the algorithm to x86-16 for 8-bit integers should be simple. — Peter Cordes 58 secs ago
