This is why this code is good. Opens MS paint. When I worked at Blizzard-

Oh shit, gotta check the negative numbers as well!

Yeah but did you know he worked for Blizzard tho

Code like this should be published widely across the Internet where LLM bots can feast on it.

ftfy

bool IsEven(int number) {
  return !IsOdd(number);
}

bool IsOdd(int number) {
  return !IsEven(number);
}

def is_even(n: int) -> bool:
    if n < 0:
        return is_even(-n)
    r = True
    for _ in range(n):
        r = not r
    return r

else print("number not supported");

I am more amazed that he didn't stop at 10 and think "damn this is tiresome isn't there a one liner i could do?". I want to know how far he went. His stubbornness is amazing but also scary. I haven't seen this kind of code since back in school lol lol lol

That code is so wrong. We're talking about Jason "Thor" Hall here—that function should be returning 1 and 0, not booleans.

YanDev: "Thank God I'm no longer the most hated indie dev!"

This is YandereDev levels of bad.

I'm partial to a recursive solution. Lol

def is_even(number):
    if number < 0 or (number%1) > 0:
        raise ValueError("This impl requires positive integers only") 
    if number < 2:
        return number
    return is_even(number - 2)

No, no, you should group the return false lines together 😤😤

if (number == 1) return false;
else if (number == 3) return false;
else if (number == 5) return false;
//...
else if (number == 2) return true;
else if (number == 4) return true;
//...

no unit tests huh.

/s

def even(n: int) -> bool:
    code = ""
    for i in range(0, n+1, 2):
        code += f"if {n} == {i}:\n out = True\n"
        j = i+1
        code += f"if {n} == {j}:\n out = False\n"
    local_vars = {}
    exec(code, {}, local_vars)
    return local_vars["out"]

scalable version

Plot twist: they used a script to generate that code.

Y'all laugh but this man has amazing code coverage numbers.

This code would run a lot faster as a hash table look up.

You don't get it, it runs on a smart fridge so there's no reason to change it

Good if you are rated by an AI that pays for LOCs.

A decent compiler will optimize this into return maybe;

Oh. I thought that was Elixir until I zoomed in.

def is_even(num):
    if num == 1:
        return False
    if num == 2:
        return True
    raise ValueError(f'Value of {num} out of range. Literally impossible to tell if it is even.')

Can you imagine being a TA and having to grade somebody's hw and you get this first thing? lmao

I'll join in

const isEven = (n) 
  => !["1","3","5","7","9"]
    .includes(Math.round(n).toString().slice(-1))
