@KrzysztofSzewczyk I attempted to program in Malbolge and Seed but they are just too unbelievably hard for a novice programmer like me

BrainF*** is way easier though

cmc: given a list of words, rotate all the words at even (1-indexed, or odd if 0-indexed) indices by 1, a b c d e f => a f c b e d

cows quack really this and fact is do => cows do really quack and this is fact

@primo @JoKing Is the behaviour of [\R+] 1…10 in perl6 to be expected. I would've thought that it would be the same as [\+] 1…10 since + and R+ are the same?

caird coinheringaahing

Thinking about posting this later today, any last feedback?

Adám

@cairdcoinheringaahing Isn't the case handling an unnecessary complication detracting from the core challenge?

H.PWiz

It seems that [\R,] doesn't reverse the list in the same way. Although I don't understand , well

caird coinheringaahing

@Adám I was thinking about that, especially given that the program I was using took lowercase input

Adám

@cairdcoinheringaahing So yes, just let input and output be in a single (answerer-selectable) case.

caird coinheringaahing

10:34 AM

@Adám Yeah, that seems like the best idea

primo

@H.PWiz it's certainly not what I would expect

scanl(+) and scanl(flip (+)) are identical in Haskell

Is it an Acronym? This challenge is trivially simplified (not copied verbatim, that will be disrespectful to the original question-maker) from @caird coinheringaahing's deleted sandbox post (I can't remember the title, is it "Is it an acronym"?) I don't remember the whole post. I think the post...

@H.PWiz That's weird... Some testing, it seems the junction operators &,| and ^ work as we expected, alongside the unlikely =. Even custom functions reverse the list rather than the order of arguments

H.PWiz

Right. It does seem like it could be occasionally useful like sum [\Rdiv] 99…1,10**100. Since it's easier to put the 10**100 on the right. (At least I don't know how the to put it at the start of the list)

I tried to use this on golf.shinh.org, but their perl6 is old, and it doesn't reverse the list

Jo King

i think it might be worth creating a bug report, since it seems rather inconsistent

right now it seems like it's acting more like [\+] [R,]

CMC: Remove only the first instance of each element in a list

[1, 2, 3]           --> []
[1, 2, 3, 1, 2, 3]  --> [1, 2, 3]
[1, 1, 2, 1]        --> [1, 1]

H.PWiz

@JoKing It seems that it's because R reverses the associativity. And then, that [\f] a,b,c,d appears to just keep track of intermediate computations of a f b f c f d

Boyer–Moore majority vote algorithm

The Boyer–Moore majority vote algorithm is an algorithm for finding the majority of a sequence of elements using linear time and constant space. It is named after Robert S. Boyer and J Strother Moore, who published it in 1981, and is a prototypical example of a streaming algorithm. In its simplest form, the algorithm finds a majority element, if there is one: that is, an element that occurs repeatedly for more than half of the elements of the input. However, if there is no majority, the algorithm will not detect that fact, and will still output one of the elements. A version of the algorithm that...

no context. just interesting

It's smart as heck

DJMcMayhem

~~Wouldn't that fail for something like 1, 0, 2, 0, 1, 0?~~ Nevermind, it finds majority, not mode

@KrzysztofSzewczyk Do you have a tutorial on Malbolge?

You know what?

I'm going to try Malbolge again!

@ngn I never knew cows could quack

I feel enlightened now

Krzysztof Szewczyk

@MilkyWay90 I didnt bother writing one myself

so I'm really sorry, as I cant recommend anything

maybe you should try esolang wiki page on malbolge?

@ngn I coined it randomly years ago and the phrase became popular in the class, so it's like my signature phrase

@Cowsquack The quacking cows!

@MilkyWay90 I think clang comes standard

oh

I already found that Homebrew supports Malbolge, so I may as well do that

Are there any normalized malbolge interpreters?
