pff, i aint reading all that, lemme optimize it:

private bool isEven(int number) {
    return rand() < 0.5;
}

Ffs just use a switch. It's much faster!

This is what Test Driven Development looks like

[–] normalexit@lemmy.world 13 points 3 days ago (11 children)

TDD has cycles of red, green, refactor. This has neither been refactored nor tested. You can tell by the duplication and the fact that it can't pass all test cases.

If this looks like TDD to you, I'm sorry that is your experience. Good results with TDD are not guaranteed, you still have to be a strong developer and think through the solution.

You could use a loop to subtract 2 from the number until it equals one or zero

[–] TimeSquirrel@kbin.melroy.org 8 points 3 days ago (7 children)

Or literally just look at its binary representation. If the least significant digit is a "1", it's odd, if "0", it's even. Or you can divide by 2 and check for a remainder.

Your method is just spending time grinding away CPU cycles for no reason.

What should all the non binary people do then you bigot

[–] theherk@lemmy.world 4 points 3 days ago

Wasn’t the fun the CPU cycles we wasted along the way?

bool isEven(int value) {
  return (int)(((double)value / 2.0) % 1.0) * 100) != 50;
}

assert IsEven(-2);

This joke was not written by the dude pictured. The author wrote a book of funny code jokes.

No need to reinvent the wheel. Use the isEven API!

[–] last_philosopher@lemmy.world 4 points 3 days ago (1 children)

To be fair, the question is "Write a function that simultaneously determines if the number is even and works as a timer"

sleepSort meets sleepIsEven

What you do is use a for loop to generate a million lines for you, then paste it in. Writing it manually is moronic. You can easily make it support numbers above 1,000,000 too this way, talking about scalable

that's some good code right there

[–] 6stringringer@lemmy.zip 2 points 2 days ago

Thanks to goodness, finally. A (giggle & snort) solid algorithm. There ya’s go set yer clocks & go get a haircut.

I hope that the language's ints are at most 32 bits. For 8 bits it could even be written by hand & the source code for a 32 bit version would only take up avg_line_len * 4GiB space for the source code of the function. But it might take a bit of time to compile a version that supports the full range of 64 or 128 bit ints.

My mate, Paul, says all numbers after 700 repeat so we can stop there.

We just give them different names so you think they're going up.

[–] segfault11@hexbear.net 6 points 3 days ago

all you have to to is throw an exception if the number is bigger than 100, who even needs numbers that big anyways?
