@Downgoat The CLA doesn't work at all for me. As soon as I enter more than one character, everything gets truncated. Also, how do I add additional CLAs?

Downgoat

crap :| did not test all browsers so just a POC

I was thinking CLAs should be split as \S+ or strings

Dennis

In what browser did you test it? It looks quite interesting in Firefox.

Downgoat

Safari, and chrome 54

at least partially in chrome

Dennis

Chrome 54 is giving me the CLA issue. The CLA works fine in Firefox, but I have to scroll down to see the I/O fields.

Are you sure? My client uses it as well.

@Downgoat For CLA-heavy languages like Jelly, I don't think that's a good idea.

it seems like the border is calculated incorrectly but rendered correctly. (or the other way around)

H Walters

Eg, supposedly with 7d 8h 10c Jd, 9d, 9h, 9c, and 9d all tie... but 9d appears slightly worse to me

Geobits

Why would it be worse? Suit only matters to a straight if it's also a flush.

H Walters

@Geobits Because there are only 52 cards and there are other players

Geobits

Ah, so you're saying 9d is least likely to prevent a flush?

If that's the case, then yes, you're obsessing :P

H Walters

9h, 9c, and 9s deny straight flushes that 9d doesn't

Yeah, I think I am :)

Geobits

Hmm. It doesn't say whether the river card is communal or not.

Half Life 3 was actually used as an example by one of my interviewers during the whiteboarding part. :P

H Walters

I've seen my share of code that has redundant, useless comments that are basically a slightly reworded version of what the code says. I'd bet you could write an "auto-commenter" that does that

Don't know how you can cheese your way out of tests though

feersum

It's easy if your program is a programming language.

I simply put my answer and the test cases as tests for each code golf challenge I answer in it.

Downgoat

> 1. A clear specification of what constitutes a correct submission, so that it is possible to indisputably decide whether an entry is valid or not. Test cases are highly encouraged.
2. An objective primary winning criterion, so that it is possible to indisputably decide which entry should win.

aren't these two like the same thing in essence?

Nathan Merrill

nope

one determines what an acceptable submission is

one determines what the winning submission is

feersum

Wait, you mean having the shortest code and giving the correct outputs aren't the same ??

Downgoat

04:45

@NathanMerrill ah

H Walters

05:10

Egads... I must be tired... I wasn't obsessing enough earlier. Given 7d 8h 10c Jd, and a non-communal river... 9s is unambiguously the best card.

And I think even 9c is second best, 9h third best, 9d last... they all have a preference order, none are tied

Geobits

Why 9c over 9h? High club straights are blocked by your 10c, but not high hearts.

Not that it really matters what rank if your opponent pulls a straight flush

PhiNotPi

@LuisMendo I created a repo for a bunch of my Bernoulli Factory code: github.com/PhiNotPi/BernoulliFactory I've slowly been accumulating a bunch of classes for a bunch of different operations/formulas.

for example, I define x/(x+y) by means of a recursive algorithm: new Or(new Mult(new Neg(y), new OverSumMinusProd(x, y)), new Mult(x, new Neg(this)))

H Walters

05:34

Geobits: That's exactly why. 9h prevents 10 high heart straight.... and therefore, very slightly increases your chance of winning; say, instead of 9h, they happened to get 9c and thus a 10 high straight non-flush. Then you win.

These are really tiny things but possible

9c doesn't rule out anything along those lines; I think it's just better because of odds, since you have 2 diamonds and only 1 club, of simple flush

(better than 9d that is)

Okay, leaving again... got to watch this cat and then get sleep

Egads... the logic's right but I mixed up the cards... 9s prevents 10 high spades; 9c prevents 9 high clubs, 9h doesn't really prevent anything but flushes. There, now the chat record's fixed despite my brain being fuzzy

(Still, "prevent 10 high spades" includes having 10 high straight non-flushes, etc)

Geobits

Since you have the 8h, the only thing 9h blocks is 9-Kh. On the same note, 9c only blocks 5-9c, since you have the 10c.

Both would beat you though, so since they block one hand each, I'm not sure it matters.

But yes, spades is clearly best and diamonds worst ;)

I mean, yes, both c and h lower flush odds too in addition to straight flushes, but the same amount for each, and they all beat a straight.

Qwerp-Derp

06:07

Hello

Steven H.

Hi

H Walters

Right, but 5c 6c 7c 8c 9x does not beat you, when x is s, h, or d. More specifically, 5c 6c 7c 8c 9x cannot beat you, unless x is c. 3 of the 9's lose, one wins. You don't want that one win...

There is no symmetric scenario with hearts., where you get this specific preference.

SpaceX asked permission for over 4000 satellites that can provide 1 Gbps low latency internet to the whole world. businessinsider.com/…

I don't think that takes 4000 satellites. Sat internet can already provide up to 50 Mbps (for consumers). Seeing how the technology improved since the satellites launched that power the current one, we might need fewer, but beefier ones for Gigabit. Still, there is absolutely nothing you can do about the horrible latency.

Does the interpreter crash because of lazyness or does it return a proper error like "you can't revisit a square you already passed on"?

Qwerp-Derp

@Fatalize It returns a proper error

Fatalize

<<
Value: 0

Shouldn't that crash? Or is the counter at 1 initially?

Or does it divide by the counter after incrementing it?

Qwerp-Derp

The counter is at 1 initially

Fatalize

Move west: Divide the value by the counter (value /= counter)

Qwerp-Derp

Don't worry I got confused

Fatalize

so I assume < will compute 0/0

Qwerp-Derp

Wait what

Whoa also what is prolog it seems kule

@Fatalize Are you still there?

Fatalize

Yes

What does < do if it doesn't do 0/0?

because from what I read that's what it does

@Qwerp-Derp It is cool indeed. Try it!

Qwerp-Derp

09:59

@Fatalize It errors

Fatalize

but in your example you say that << results in 0 instead of an error

Qwerp-Derp

10:17

Wait whoops

Uhhh

It does 0/1

Which equals 0

And then 0/2

I just saw 0/0 and < so I assumed you were talking about the sidecase

I got confuse :(

when you start the counter is 0 and the value is 0 right?

@ArtOfCode The goat was having really weird problems with ChatExchange authenticating. If you could take a peek at the errors in the transcript that would be great

@Lembik Would that be equivalent to the partial sums of a series of non-negative integers? Would you want the jumps to be arbitrarily large or chosen from a defined range?

TimmyD

14:17

@Geobits I was really stressing out, because I couldn't think of a way to shorten the code any, until I came into work this morning and said to myself "Why don't I just generate 'em all and check membership?" Lo and behold, way shorter.

Lembik

@trichoplax the idea is to specify a random 1... n and say that the list of k integers must be from 1..n and the list must be uniformly chosen from all non-decreasing lists of that length

Geobits

@TimmyD Oh, I'm surprised you hadn't tried that yet, since a couple answers use it.

trichoplax

@Lembik Does non-decreasing allow for k>n?

Lembik

@trichoplax no

trichoplax

Is 1, 1, 1, 1 non-decreasing?

Lembik

yes

trichoplax

Or are the numbers chosen from the list without replacement?

Lembik

1,1,1,1 is non-decreasing

the only tricky part is the unformity requirement

trichoplax

Is k specified as an input, or must you choose over all possible k?

@Geobits Yeah. It wasn't until this morning that I actually saw those other answers. On harder problems like this one, I generally try to avoid "spoilers" for myself to see what sort of solutions I can come up with independently.

@TimmyD I do at first. I don't usually change mine to a direct port of anything I've seen, though, since it normally ends up longer in Java anyway :P

It's time for Processing to enter the stage

@Poke I knew there had to be something :)

The art of raising prize-winning pigs.

14:24

I said no such thing.

Geobits

So that should be prize-winning rams :P

TimmyD

@Dennis Eleven abuse to the extreme.

Poke

I might be able to use numbers too... honestly anything to get that arrayCopy out of there

Lembik

@trichoplax it's specified in the input. The input is n,k

Geobits

Yeah, I tried the arrayCopy thing. Too bad Java doesn't have a shorter slice.

Lembik

14:26

@trichoplax some sort of time limit will need to be imposed otherwise there is a wildly inefficient solution

Geobits

Tried the recursive method with Strings too, but that was a disaster.

150 or so

So many charAt() :(

Poke

yeah charAt and even substring

trichoplax

@Lembik Generate all valid sequences and pick one at random? Or generate all sequences of length k (valid or not) and keep picking one at random until it's valid?

Poke

or if you tried to go with a character array with string input .toCharArray()

/me shudder

Lembik

@trichoplax right.. both should not be allowed :)

they are easy to ban by saying the code must run in a few seconds for n = 100 and k = 10

trichoplax

14:29

I still don't follow why k<=n. Is that just a rule of the challenge?

Lembik

@trichoplax oh I see.. maybe we don't need that restriction

good point

trichoplax

I don't know if the restriction allows more approaches or not. I don't have an intuition for what approaches are possible yet

Lembik

let's cancel that restriction :)

trichoplax

So for n=2, k=2 we have
1, 1
1, 2
2, 2
each with probability 1/3

Free Amazon Prime month ended one day before The Grand Tour starts. >:U

Kritixi Lithos

14:33

When does Grand Tour start?

mınxomaτ

...

In one day.

But only in the US, UK, Germany and Japan.

Lembik

@trichoplax yes

@mınxomaτ and also on the Internet.. cough

Kritixi Lithos

That sucks. They should release to more parts of the world. For example, the new Top Gear (with the new hosts) were available online on a BBC site

Lembik

@KritixiLithos it doesn't really stop anyone watching it does it?

Kritixi Lithos

@Lembik You got a point there

mınxomaτ

14:37

They could enact the new Top Gear right in front of me for free and I still wouldn't watch it.

trichoplax

@Lembik I'm not sure if it's a duplicate but the uniformity requirement makes it sound new to me

The Grand Tour: A Message from the Guys

Very relevant.

Lembik

@trichoplax cool

trichoplax

The sandbox should clear that up though...

Q: On this site we obey the laws of thermodynamics!

And in particular the second law: the entropy of an isolated system increases over time. For this challenge, An "isolated system" will be taken to be a program or function (abbreviated as "program" from now on); The passing of "time" will correspond to iterated executions of the program's outp...
