I got my first edit on OEIS approved! :)

oeis.org/A049064

Dennis

\o/

I am Vioz- on Stack Exchange.

Proof and everything. :P

Vioz-

Haha :P I kind of wish I could figure out how to edit it now

Since you're here and you know CJam, this is what I came up with for #1 in the decathalon: q~,{2#}%{+}*

This looks kind of long for the task at hand

Dennis

2# won't work well for cubes.

Vioz-

Oh turd, didn't realize it was cubes, not squares :P

So 3# then for that bit

Dennis

It's shorter with the infixes f and : Sp3000 recommended.

{binary}* is just :binary.

{argument binary}% is just argument f binary.

Vioz-

10:13 PM

Cool, so that gets me down to 8 :) q~,3f#:+

I think that's as good as it can get, I have no clue though

Dennis

That works.

7 is the shortest for CJam, but that requires some trickery.

Vioz-

I don't think I'm ready for that yet :P

In CJam, if I have a stack like [[a b c d] n], how do I get the nth element from [a b c d]

Dennis

=

Vioz-

Yep, just figured that out :) Thanks!

Martin Büttner

@Dennis s/yet/any more/

Dennis

@MartinBüttner I admit it. I was too lazy to go through the question's timeline. :P

Martin Büttner

I'm not even sure it's possible to find out its vote history, but I remember that it was just about valid at some point and is now quite far off the 2:1 ratio

ohhh

first n non-negative

removed the spoiler :D

Vioz-

10:52 PM

Why should 1 return 0 for #1 D:

That means 2 should return 1?

Martin Büttner

yes

"first n non-negative" means it starts at 0

the first three non-negative cubes are 0, 1, 8

Dennis

@MartinBüttner Going through meta.codegolf.stackexchange.com/posts/1061/timeline and counting the votes for hosch250 should work, but I don't feel like doing that. :P

Vioz-

I'm dumb

Martin Büttner

@Dennis what the... I have never seen that page

is there a link to it anywhere?

Vioz-

I think #9 in cjam is probably my best bet at having a short one, unless Pyth is < 6 bytes for that

Dennis

10:54 PM

Only in some user scripts.

I wish people voted more. The highest number of votes of all decathlon answers is 2 right now, but 8 users have already answered the question.

Dennis

@MartinBüttner Just saw the notification. Yes, that's the one.

Nobody found it yet. I bet that would be shorter in most languages.

Correction, somebody already did. Sort of. The entire approach is quite different.

Vioz-

Do Python 2 and Python 3 count as separate languages? :P

Geobits

Watch out, it'll be pyth 0.1, 0.1.1, and 0.1.2 competing next ;)

Dennis

@Vioz- Nope. Footnote 1 says: Languages count as different if they are not different versions of the same language, so there's only one JavaScript and one Python, but C and C++ are two different languages.

Vioz-

Ah, ok, I missed that

Dennis

11:23 PM

@Vioz- You CJam code will only work for 2-dimensional arrays.

Vioz-

Darn, ok
