@FryAmTheEggman It turns out that the language you were looking for was 05AB1E :-)

Does MATL have a function for determining if an input is a letter?

I have 65:90 97:122hm which is ridiculously long.

I suppose you could do 65:90t32+h instead, which is 3 bytes shorter.

Oh, also congrats on the 20K Luis!

@DrGreenEggsandIronMan I think k2Y2m does what you want

Thanks! :-)

I saw you linked @Suever's interpreter. Do you think it's safe to use it yet? What do you think, Suever?

IDK if it's safe to use or not.

I Just prefer it because of the documentation.

D you think I should link to TIO instead?

@LuisMendo That doesn't quite work. It just pushes the lowercase. I have to do 2Y2tXkh

@DrGreenEggsandIronMan Yea for now I'd use TIO.

I should generate a button to generate the TIO link from the new one

because it is easier to mock up an answer on the new one I think

but it's not quite ready for prime-time

@DrGreenEggsandIronMan It pushes the lowercase, but the input is also converted to lowercase with k

We are close to it being stable though. I'm working on all of the testing as we speak

@LuisMendo Yeah, I get it. Cool hacky method.

Too bad I can't use it cause of that stupid last test case.

@DrGreenEggsandIronMan Did you see my comment in the answer? Unfortunately last test case seems to fail

Ninja'd

Yeah, I saw it. I don't want to delete though. :/

I will, but it's going to be painful.

Yeah it's a pity

For a brief beautiful moment, I was beating you. :P

On the other hand, that makes me the current winner :-)

Haha. Ninja'd again

Oh, the Retina answer is 18

I think I'm going to edit your tips in before I delete so that users who can see deleted answers see that I (kinda) beat you. :P

That's a good idea. Make the answer as good as possible inspite of some case failing

Woah, I (kinda) beat retina!

CPU usage for matl.suever.net is kind of a joke

@Suever :-D

Granted I have it set to scale between 2 and 4 octave workers

but the nice thing about Amazon's EC2 is that you can get extra burst CPU so you can surpass 100% as needed

and all the time that you spend below 100% accumulates and helps count towards how long you can burst

So when someone needs one of those computationally intensive challenges we're good to go
