idk about you, but I always use socks for my puppets. Shoes just don't work that well, and hats are abysmal

Q: Park, Lake, Santa Fe

Given a long multi-sentence string, the goal is the count the occurrences of the following words: park, lake, Santa Fe. The words can appear as substrings of other words, i.e, "parked" counts as an instance of "park" since "park" is a substring. The output should be three numbers separated by spa...

Unrelated String

3:52 AM

exams are by far the least shit part of education in my experience

Bubbler

Exams can be fine, but they can also be very shit

lyxal

Exams such as maths and essay writing subjects are usually fine

But programming exams are the opposite

Because unlike us, they don't follow the rule of having objective criterion

And you can't VTC the exam questions as unclear and wait for them to use the sandbox

my only experience with programming exams was having to handwrite java for ap csa

Hopefully that's not still a thing

and that was
silly
but the test itself was so far beyond fucking braindead that handwriting java was literally the biggest challenge

Bubbler

How can anyone even do that

Is it faster to multiply two single-digit numbers or use a lookup table?

Also what happened to the HW feed?

Bubbler

@Ausername Faster for a machine or a human?

A username

Machine

Also is there any difference for larger numbers?

Bubbler

I guess multiply wins over lookup for register-sized numbers and output

and lookup is pointless (you can't store that large lookup table in a reasonable machine) for something larger than that

A username

That makes sense

Hello, World!

A: "Hello, World!"

GForth 17 Bytes ." Hello, World!"

Bubbler

Register-sized multiplication is 1 instruction and takes at most 2~4 times the time to do a register-sized addition. 2D lookup table takes a multiplication by constant, an addition, and then a memory read. Even if you use a power-of-2 size to replace multiplication with shift, it's at least two instructions, and a memory read can get very slow on cache miss.
