Q: Is it a Cyclic number?

A cyclic number is a number of "n" digits that when multiplied by 1, 2, 3,...n, results in the same digits but in a different order. For example, the number 142,857 is a cyclic number since 142,857 x 2 = 285,714, 142,857 x 3 = 428,571, 142,857 x 4 = 571,428, and so on. Given an integer input, det...

@Mego Does my message being trashed reflect badly on me?

Dennis

I hope not. I have to trash my own messages all the time.

@Christopher Not really. There was just no reason to keep it around with the rest of the messages gone.

@HyperNeutrino There's no such thing as an auto-kick.

user165474

Ah ok

Anonymous

@HyperNeutrino There are no such things as autokicks. Being kicked doesn't make you a bad person. It just means "seriously stop it, take some time to think about what you've done"

ah. okay. point taken, promise it won't happen again.

Though auto-kicks would be an interesting idea... Adapt Smokey to be a room owner

C&R idea . Cops write a solution and make it verbose. Robbers try to make it as short as possible. It is cracked if they get it down to the cops original byte count or lower

Hmm would it be a dupe with same outgolf idea but with a harder challenge?

Destructible Lemon

anyone wanna help with my koth?

Christopher

Depends. What do you need?

Destructible Lemon

people to tell me that it is ok to use functions

Downgoat

@ASCII-only how are we going to do union types

Christopher

12:23 AM

@DestructibleLemon it is ok to use functions

Destructible Lemon

I mean as the bots, when they have persistent memory

Downgoat

ordered dict (OrderedDictionary<K, V>) is basically sugar for: (Tuple<K, V>[]) right?

they both have O(n) search time

or do ordered dictionaries also do hashing

feersum

Ordered dict as it's usually understood has log(n) search time.

Downgoat

binary search?

Destructible Lemon

should I just say that class variables are not allowed in my koth?

feersum

12:25 AM

err actually it's not so clear, it can referred to multiple things

Destructible Lemon

and use classes?

feersum

but definitely not O(n) search.

ASCII-only

@Downgoat maybe dictionary + vector?

Destructible Lemon

I probably should

also I need people to say they are interested in my koth

Downgoat

@ASCII-only ?

ASCII-only

12:26 AM

like every key and value would have Object *next or whatever

Christopher

Interested in my koth

Downgoat

@ASCII-only so linked-list of (K, V)?

Christopher

@DestructibleLemon sound good?

@Downgoat kinda, it's dictionary that also has a way to use as linked list

Question: I basically have a set I, and set V (I subset of V), how to effectively binary search their difference?

Helka Homba

if I is subset of V then isn't intersection just I?

Downgoat

sorry, not thinking, meant difference

do i just search through V, and if i is in I, then skip it?

that seem wrong because I'm doing whole set

Question: should Int -> Double conversion be implicit (where the type has been explictily been specified as Int)

Wheat Wizard

@DestructibleLemon I'm not a fan, I like take n get the nth smallest one.

Destructible Lemon

maybe generate an infinite output

Anonymous

@Downgoat I don't think so. Only when doing arithmetic with a double should an int be implicitly converted to a double

Wheat Wizard

:( A lot of esolangs can't do that. These challenges are most fun for esolangs in my opinion.

what is the consensus on unary input for languages that can take decimal input, (but where it is very much simpler to take unary input, based on how the language arithmetic works)?

Downgoat

@DestructibleLemon If like in JS I took 11111 that would be eleven thousand, one hundred and eleven. Not 5

do you mean something like retina?

Destructible Lemon

nope, specifically Turtlèd

Downgoat

I mean it can pass a unary number which is interpreted as decimal natively as "unary", but if it actually is a base-1 number than sure

Destructible Lemon

1:12 AM

turtlèd can get decimal input

Downgoat

@DestructibleLemon off-topic: why call turtlèd and not goatèd :(

Destructible Lemon

because it is the standard

maybe if you went back in time and got the turtle called a goat instead...

@ASCII-only I've added unicurses support to Klein, can't test it on windows but it works for me

Nathan Merrill

1:59 AM

is there a single word for "strictly increasing, and contains no jumps"?

Mendeleev

@Downgoat There is x^2-c

Downgoat

@Mendeleev pls tell secret to solve such equation

Nathan Merrill

@Downgoat sqrt(-c/a)

Downgoat

not how to solve, solve is easy, how to factor

feersum

@NathanMerrill What do you mean "jumps"?

Nathan Merrill

2:00 AM

1,2,3,5,6,7

Mendeleev

which is (x+sqrt(c))(x-sqrt(c))

If you have a solution, you have a factorization.

@Mendeleev oh

where a=1

Downgoat

nobody cares about you quadratics, goatratics are obviously better

Mendeleev

It's my second math class this year so I'm going to be finishing it over the summer

but I finished algebra 2 so that's my main class this year

Downgoat

>_> so we are in same boat then :P

are you going to physical school or doing online

Mendeleev

online math and language, everything else is physical

Downgoat

@Mendeleev what additional class are you taking that you have to take math and language outside of school O_o

Mendeleev

This is a tough question

My school is "innovative" uses project based learning thing so I do everything else through projects

actually

the discriminant is what's inside

@DestructibleLemon why 10%

@DestructibleLemon Yes

Destructible Lemon

@ASCII-only arbitrary number

ASCII-only

Do a round robin, see who wins most often

@DestructibleLemon doesn't 10% mean loss

Destructible Lemon

so, I count every single game, not the result of matches?

ASCII-only

@DestructibleLemon Hmm the result then

Destructible Lemon

3:50 AM

actually, there is no specific result

match is the highest level of competition between bots. it is 42 games, which are made of rounds until someone loses 5 rounds, or wins 5 rounds, and rounds are made of turns
