huh, even with how active I am in TST I've still sent 2k more messages here

CMC: Given a the list of prime factors for two numbers, return the prime factors of their sum. fastest-code

I'm pretty sure there's no faster way to do this than just prime factorize the sum of a and b's products...

you could factor out the intersection

@ATaco 0 bytes, assuming interpreter is running right now and in the northern hemisphere

@mousetail Didn't work for me. :P

Did you test at the exact moment when I posted the message?

ATaco

@mousetail Does IT support ever provide favourable conditions?

exec(input())

Wonder if you could do a real one with ctypes

CMC4real Given raw machine code as a byte string, make your processor physically jump to it

Maybe if you spin the fans fast enough

CMC: Rencontre numbers. Given n and k, output the number of permutations of [1, 2, 3, ..., n]with exactly k fixed points

I'd post on main, but there's an incredibly trivial answer once you can calculate derangements

In fact, I have 7 bytes in Jelly, same length as the Jelly answer to Compute the Subfactorial

Ugly brute-force 8 in Vyxal: ɾ:Ṗ$v=ṠO

I don't think vyxal has derangement/subfactorial builtins

caird coinheringaahin g

If it does, it should be able to do it in around 4 bytes

Maybe 1-2 more due to stack manipulation

If Jelly had subfactorial as a builtin, it'd be 4 bytes. Chaining really helps for it :P

@mousetail GolfScript, 1 byte ~

because you can run arbitrary ruby in string literals

is some variable lookup struct made of both a stack for scoping and a HashMap for finding too complicated for a 2-d-matching language? for Fortnightly Ch. #6.

noodle man

i haven't read the whole challenge, but that seems like it could be helpful

at least some kind of structure to store previous matches

hashmap feels a tiny bit overkill but it could fit if you did it right

Jan H

23:10

one of the types only has one-character names so it can go into matrices in the code; would HashMap<char,Generalization> be overkill then?
