@DrGreenEggsandIronMan I once did on Christianity.SE.

Nathan Merrill

if I were doing the challenge, I'd totally include a test case with 1000s of lines, and put a time limit

WHOOHOO 500 consecutive days on the main site! :D

That streak was broken 11 days later.

Downgoat

@El'endiaStarman :(

Mᴀʀs Uʟᴛᴏʀ

then it's something like triangular number squared - columns * dupe rows - rows * dupe columns + dupe rows * dupe columns?

El'endia Starman

@Downgoat I was sad too.

Mᴀʀs Uʟᴛᴏʀ

00:02

@NathanMerrill is there even any fast way to find duplicates

Dr Green Eggs and Iron Man

@El'endiaStarman nice. I'm at 208 rn, which is my record.

Also, awesome chatroom name. :)

El'endia Starman

Thanks. :D

Nathan Merrill

actually, finding duplicates isn't the solution

Mᴀʀs Uʟᴛᴏʀ

how can you do the challenge without enumerating anything

Nathan Merrill

I think you calculate the number of unique distances for each of the axises

Mᴀʀs Uʟᴛᴏʀ

00:05

yeah, that's not fast enough either

Nathan Merrill

@R.Kap better. Because you are simply indicating the number of columns/rows, you don't need to include the word "unique" (and it is confusing that way)

R. Kap

@NathanMerrill All right. I got rid of "unique".

Nathan Merrill

R. Kap

@NathanMerrill Yay! \o/

@NathanMerrill Also, if you have the time, could you see if there are any questions currently on PPCG that my proposed challenge could be marked as a duplicate of if it was posted on the main site? I would really appreciate it.

xnor

@R.Kap actually, i don't understand the problem. why does [2,2] give 36?

Leaky Nun

@xnor I believe he meant [3,3]

Any way, the formula is just [m,n] -> m(m+1)n(n+1)/4 (Yes I'm fun at parties)

xnor

@LeakyNun i thought the same but then [6,7] -> 550 is a mistake?

Leaky Nun

@xnor he may as well have miscounted [6,7] seeing that he doesn't even know that this challenge is that trivial

he may have counted it by hand

xnor

02:11

i see

yes, that's definitely trivial

though i think the python shortcut n*~n*m*~m/4 is cute

@Mego That's harder than it sounds. Curating the list of versions manually for each language is impractical, and I can't think of a better way.

Also, congrats!

@Dennis For languages that use package managers, it'd be pretty simple. For others, version control commits could be used.

Dennis

Getting married was the most rushed and best decision I ever made.

Nathan Merrill

so, before each TIO request, the server would do a git checkout?

El'endia Starman

02:43

@NathanMerrill Looks like my first chat message was in September last year, so yeah, you got married before I really joined.

September 16, to be precise, which means its after histocrat's too.

ah. I checked your PPCG join date

@xnor Because a 2 by 2 grid of rectangles results in a total of 36 different rectangles if you look really carefully.

@xnor Well, I tried doing that, but it is even more confusing as creating those squares would resulting in many overlapping ones, hiding ones that are supposed to obviously be there.

@LeakyNun shorter

@LeakyNun see also my comment on your challenge :)

Leaky Nun

@orlp replied

orlp

@LeakyNun what about (5.0, -3.0)?

. is not a digit

Leaky Nun

@orlp does it match the regex?

orlp

no, because it sees that as 4 numbers

unless \d contains .

which I don't know

Leaky Nun

@orlp then that's a no

orlp

04:00

well

it entirely depends on \d

Leaky Nun

@orlp AFAIK no implementations of \d contain the dot

orlp

"The format of the position consists of two numbers separated by any non-empty string that contains no digits."

I'd argue that 5.0, -3.0 is two numbers separate by a non-empty string that contains no digits

your regex just has a flawed concept of what a number is :)

Leaky Nun

@orlp you win

I like the animated gif. It's like the perfect way to show all the rectangles.

so checking a number is of the form floor(n*n/4) = x

Leaky Nun

@NathanMerrill I don't get it

Nathan Merrill

also, pretty GIF

Leaky Nun

@Mego Do you have any intention to include extended commands?

Nathan Merrill

@LeakyNun with the numbers [1,2,3,5], you have 4 possible ranges. 1->(1,2), 2->(1-3),3->(2->5),4->(1->5)

Leaky Nun

@NathanMerrill Eh, I doubt if that is how the word "range" is used

Dmitry Kudriavtsev

@LeakyNun What do you find "bad" about that challenge?

Nathan Merrill

@DmitryKudriavtsev the broad part of the challenge is "It should support executing single commands and evaluating expressions, but supporting more complex constructs is not required"

Dmitry Kudriavtsev

nd?

Dr Green Eggs and Iron Man

Here's more concrete thoughts. 1. "Extra credit" is never a good idea for code golf 2. It's either boring and trivial, or extremely difficult depending on the language.

Nathan Merrill

@DmitryKudriavtsev right, but what if my language doesn't have such constructs?

Leaky Nun

@Mego so will you?

what if I only accept addition

so, if you type in "4+5", it'll work, but anything more complex, it won't

Downgoat

@Mego Congratulations!

Nathan Merrill

is that valid?

xnor

04:44

@R.Kap the presentation is great, but the challenge is totally trivial because there's a formula

n*(n+1)*m*(m+1)/4

Leaky Nun pointed it out earlier

Anonymous

@Downgoat Thanks :)

Nathan Merrill

@R.Kap I'd totally do a part 2, where you ask for the number of rectangles with unique dimensions

Dennis

@DmitryKudriavtsev We had that discussion before. In this current form, the question is underspecified and thus too unclear for PPCG. Undeletion and reopen votes wouldn't help; the question just would get closed again. If you specify it properly, you can flag it for moderator attention so it can get undeleted.

As I've said before, a reference implementation cannot be a replacement of a spec. Porting your Ruby code to some languages might be rather straightforward, although there could be subtle differences. In other languages, there is no way to do exactly the same because they are too different. If the task is impossible in some languages, that's fine, but you still need a specification (by capabilities, not a white- or blacklist) that tells us in which languages it is impossible.

@Mego Can't you use 5²u instead of 5Pτ?

Dmitry Kudriavtsev

@Dennis I DID say that:

@Mego It would be better if you write 26 13 in the score of your answer

I remember essentially solving that spiral problem in reverse for project euler

@LeakyNun While it can be used, it offers no benefit over the current representation. Like I mentioned earlier, I use 5Pτ because that's the representation I thought of first.

@DmitryKudriavtsev That's not a spec. I'm also not convinced that it's true. Many compiled languages also have a REPL.

Dmitry Kudriavtsev

Huh?

Zwei

and you could create a brainf*** repl in C++, couldn't you?

Dmitry Kudriavtsev

What are those?

Leaky Nun

@Mego Eh, benefit depends only on the point of view

Then the challenge isn't exactly the best idea. Writing challenges specific to a language or a set of languages is too restrictive around here

REPL = read, eval, print loop

@LeakyNun I generally do not post crossed-out old scores in my answer headers. If someone is interested in the golfing process, they can look at the edit history and see the previous scores there.

oh

@LeakyNun Objectively, the benefit would be shorter code. Since it's the same length, there's no reason for me to prefer one over the other.

Zwei

I saw the challenge earlier before that part was edited in

It was edited to address the close votes.

Clearly that did nothing.

Zwei

I haven't written a challenge before, mainly because I can't come up with non-trivial challenge ideas, but have you even tried running your challenge through the sandbox?

Nathan Merrill

@Zwei the pain of coming up with non-triviality

I feel you :)

Dmitry Kudriavtsev

@Zwei Sandbox?

I have an idea for a non-trivial challenge!
