Q: Given the name of a language, output "Hello, World" in that language

Given the english-name of a top-100 language defined in this Wikipedia article, output "Hello, World!" in that language. You should use Google Translate's translation for your program. You are allowed to use the translator of your choice if it is not in Google Translate. Do not use any pre-made ...

I had an idea for a challenge like that a while back but it doesn't really work

Actually, wait.

This is different

I wanted to make a kolmogorov-complexity where you could output the string in any language

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I can't tell you how happy I am to see that people are using Jolf :D

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ I would use Jolf more if there were readthedocs docs

Maltysen

\o/ counting sheep done

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Downgoat I hate readthedocs

It doesn't work for me

Downgoat

02:07

then you're not doing it right

it worked great for TeaScript's docs

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@CᴏɴᴏʀO'Bʀɪᴇɴ I tried to use jolf, but i needs file io and running locally.

Sowee.

quartata

You can upload a file to the interpreter

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Downgoat If I knew how it worked, I'd use it

^^

quartata

I don't even use CJam locally anymore though so

Downgoat

are you using rst or markdown?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

02:10

quartata

@Downgoat Markdown

Downgoat

you have to use rst

I don't think Code Jam accepts submissions in languages other than the choices in that drop-down box during registration

Maltysen

@Mego what about graphs?

Anonymous

@Maltysen Yeah but that doesn't mean they'd have the relevant interpreters for every language

Dennis

Here's a thought: A⁺ for A, B for B, C++ for C and D for D.

Mars Ultor

leave Code Jam for later

Anonymous

02:23

@Maltysen Nope it sucks at graphs

Maltysen

@Dennis haha roflamo

why c++ for C?

Dennis

I didn't want A⁺ to feel alone.

Use nasm for all, regret life choices

BrainSteel

I assume you guys are doing GCJ, eh?

Chris Jester-Young

@quartata It's a serious Scheme implementation, with a pretty decent collection of packages (known as "eggs"). If you need good interoperability with C libraries or just want to compile Scheme code to C, it's worth checking out.

That makes FGITW brute force solutions viable

nice challenge @KennyLau

@epicTCK I would have been happy to try to help you on IRC, but you've gotta stick around on IRC a lot longer than that. :-P

A: Find the program that prints this integer sequence (Cops' thread)

Vim 36 keystrokes i****<esc>:let @q="^*i****$**@***"<cr><n>@qbD Here is the code unrelated to number generation: :let @q=" "<cr><n>@qbD Meaning I am revealing 5 out of 19 characters. <n> is the input. Here are some sample outputs: 1@q: 1 2@q: 3 6@q: 18

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I'll work on it, then not post.

That challenge is really unclear because it doesn't have a good definition of what "vital" means

Dr Green Eggs and Ham DJ

Yeah, that's true.

I'm a little sad, because It's a really cool and novel idea, but not very well executed. (as of yet)

However, I really like my answer!

Hence why I VTC'd it

@Mego I never got a response for the BF comment, so I'm VTCing for that too

@Sp3000 That URL is amusing to me because they could have spelled out vocabulary with 3 extra characters or the oft-used vocab with 2 fewer, but instead they used vocabul.

the first 2 problems are actually pretty easy

the last two problems are pretty tough

And you don't need 24 hours for any problem unless you're brute-forcing C-large in IronPython

B seems easy but I can't focus enough right now to solve it

Nathan Merrill

@QPaysTaxes Here?

@quartata but also your code

Anonymous

@Sp3000 Yeah but I think they verify using the programs after the contest

Kenny Lau

or anyone who knows JS

Nathan Merrill

@Mego actually we can

Collaborating with anyone else during any round of the contest, with the exception of the qualification round, is strictly prohibited

Kenny Lau

02:45

How would you call an unnamed function?

Nathan Merrill

we're in the qualifiers right now

Kenny Lau

@QPaysTaxes How would you call an unnamed function?

quartata

Oh well I'm too lazy to do a competition like that anyways

Anonymous

@NathanMerrill Really? I seem to remember in previous years collaboration was always forbidden while a round was going on

Mars Ultor

I'm pretty sure it's prohibited

Maltysen

02:46

for B I was thinking of using djkastra's, but large has 2**100 nodes

Nathan Merrill

its always been ok for qualification round

Anonymous

Huh, TIL

Kenny Lau

@QPaysTaxes function(H,S,n){return 0;} ?!

quartata

Seems like it would be pretty difficult to enforce in the qualification round.

Kenny Lau

@QPaysTaxes How would I call this unnamed function

in Javascript how would I call this function

Nathan Merrill

02:47

@quartata its pretty hard for the other rounds too, but yeah

Anonymous

Okay yeah, problem B is essentially flipping bits in a number, but you can only flip an entire contiguous region starting from the MSB, and flipping a region also reverses it

Maltysen

@KennyLau wrap in parens put two aprens a t end its called an IIFE

Nathan Merrill

@Mego what's MSB?

Sp3000

@Mego Well at the very least I know of one person who submitted in Whitespace, so if they do verify their language range is pretty broad

Kenny Lau

@QPaysTaxes yes

@Maltysen e.g.?

Nathan Merrill

02:47

most significant bit

nm

Anonymous

@KennyLau Assign it to a variable (like var f = function(H,S,n){return 0;}) and call it (f();)

Kenny Lau

@Mego I see

quartata

@Doorknob you broke your new year's resolution to post a question every two days ;_;

Maltysen

@KennyLau (function(){})()

Sp3000

Wait, what do you mean by verify anyway? Because there's been luck-based ones in the past

Kenny Lau

02:48

@Maltysen I see.

Anonymous

@QPaysTaxes Yep, but assigning it to a var is more intuitive IMO

quartata

@Sp3000 Whitespace is actually on ideone :P

Maltysen

@KennyLau that's how you do closures in js

Nathan Merrill

@Sp3000 later on, their servers run your submissions

so, it would be feasible then

quartata

It's kinda not very esoteric anymore hehe (at least in the sense of obscurity)

Kenny Lau

02:49

@Maltysen I see.

but for now, its simply "we give you an input, you have 4 minutes to upload an output"

And if you started on it at the start of the contest, you have 27 hours to brute-force the solution

brb skipping b going to c

Anonymous

Which allows FGITW to dominate, which is dumb

Nathan Merrill

02:53

@Mego qualifying its based on number of points, so unless you're going for the leaderboard, it doesn't matter

quartata

So basically they give a problem, and then you have to download some test cases and give the results from your program in 4 minutes?

PhiNotPi

I'm breaking out the Element: codegolf.stackexchange.com/a/77430/2867

Kenny Lau

@QPaysTaxes It works

Nathan Merrill

@quartata yes. except for C (which is an exception )

Anonymous

@NathanMerrill It does matter, because the people whose time zones are more convenient for the start of the challenge have a huge advantage in getting those points for qualification

quartata

02:54

@NathanMerrill Why do they give the test cases ahead of time on Problem C?

Kenny Lau

@QPaysTaxes Come on. How am I supposed to scan through 183 pages of result?

Nathan Merrill

@quartata the nature of the problem

@Mego if you really are bruteforcing it, then you won't get far in the challenge

Kenny Lau

@QPaysTaxes Really.

@NathanMerrill Brute force solutions work more often than you'd expect in code jam

Chris Jester-Young

@Mego Except for large dataset.

Small dataset usually does allow brute force solutions.

PhiNotPi

Actually, how was I able to add my answer here if the question was already put on hold?

Anonymous

My first time doing code jam, I make it to round 2 using mostly brute force solutions, because I had very little experience coding

like in B. you can brute force 1024 node graph, but large is 2**100

are you allowed to use third party libraries?
