Oh shit, gotta check the negative numbers as well!

Yeah but did you know he worked for Blizzard tho

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

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

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

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

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

ftfy

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

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

no unit tests huh.

/s

else print("number not supported");

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

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

This is YandereDev levels of bad.

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

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.

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;
//...

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)

pro hacker tip: you can optimize this by using "num" for the variable name instead of "number"

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

I want to assess coders by lines written! The more the better!

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

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

A decent compiler will optimize this into return maybe;

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))
