Q: Ways to add 1 to lists of lists

Adapted from this StackOverflow question In this challenge you will take a list of lists of integers, e.g. A = [[1,2],[3,4],[5],[]] And an additional single integer (e.g. n = 7). If you were to add n to the front of one of the lists in A there would be as many ways to do that as there are lists...

I do agree with Adam, that I think the explanation strings should be inputs, but that's up to you. The challenge itself looks ready to post imo

Fmbalbuena

@cairdcoinheringaahing but all explanations except NOP is exactly same from esolangs.org

caird coinheringaahing

@Fmbalbuena By requiring a set of fixed strings, a lot of answers are going to spend a lot of "trivial" bytes on those strings, and a lot of the competition will come down to which language has the best string compressor. That's fine, but some people don't like it

Fmbalbuena

@cairdcoinheringaahing Hmmm... go to changing my sandbox post.

caird coinheringaahing

11:38

Having them be inputs means that the bytes spent on getting the strings are much fewer. It's entirely up to you which you do however. This is more "Personally, I think the challenge would be more interesting if X", rather than "You need to do Y to make the challenge clear"

Either way works, some people just prefer one over the other

Q: Introducing Biweekly Mini Golf!

In order to grow our community and its chat room, The Nineteenth Byte, we decided here to start a new monthly biweekly chat event: Biweekly Mini Golf! During this event, a number of previously drafted "CMCs" (short for Chat Mini Challenge) will be posted, and anyone can reply with their solutions...

Fmbalbuena

11:54

@cairdcoinheringaahing Fixed but can you find bugs?

caird coinheringaahing

@Fmbalbuena I'd rephrase it as "The explanation for each character will be provided as input. You may choose how to associate each explanation with it's character (for example: dictionary; mapping; list where the first element corresponds to +, the second to -, etc.), but it must be consistent" Then add some test cases with other explanation texts

Fmbalbuena

I'm bad at editing.

Welcome to the 14th Biweekly Mini Golf. During this event, we'll post some CMCs (Chat Mini Challenges) for you all to solve. A new one will be added every 5 to 10 minutes. Feel free to keep suggesting drafts during the event. If you have any questions, don't be afraid to ask. Good luck!

AIDraft: Find the single most repeated character or word in a string with exactly 4 unique characters, e.g.: AAAAAAAAAAAABBBBCDDDEFFFFF -> B

in BMG Drafts, 48 mins ago, by lyxal

AIDraft: From an unsorted integer array, find the first missing positive number. e.g.: [3,-1,2] --> 1 ; [-10204433, 545371683, 156929402] --> 1 ; [1,-2147483648] - > 2

in BMG Drafts, 47 mins ago, by lyxal

AIDraft: Print out every 5th number between 1 and 100000. e.g.: [1,6,11...

those should be enough to get the party started

@PyGamer0 I feel like this is invalid, as the maximum shouldn't be the input; as stated by the test cases (10 -> 2 & 5 and 24-> 2 & 12)

PyGamer0

@lyxal but its not stated in the question

lyxal

> For example for 10 -> 2 & 5; 24-> 2 & 12 ; etc

lyxal

12:46

@Fmbalbuena correct

Leaky Nun

@lyxal Jelly, 17

lyxal

@Fmbalbuena copilot allows insertions anywhere, codex only completes at the end

AICMC: Given an array A of integers, we must modify the array in the following way. We randomly, with uniform sampling (i.e. every choice has an equal chance of being chosen) choose one element from it (A[i], where i <= N-1), and subtract 1 from every other elements.

Fmbalbuena

@lyxal can i post AICMC?

Leaky Nun

@Fmbalbuena are you an AI?

lyxal

@Fmbalbuena if it's generated by AI, then sure

you're allowed to make minor modifications/clarifications, but it has to be mostly by the AI

Fmbalbuena

@Adám well I just think it's a very funny coincidence it generated something you already asked as a challenge :)

@lyxal What should it write if given any other input?

PyGamer0

@Adám fixed

lyxal

@Adám I would say to replace spaces regardless of input.

for some reason, it just decided to include that specific string

Adám

Hold on, I thought the solution should conditionally write a function.

lyxal

13:01

I mean, that'd be a valid answer too

Adám

But then the question is what my solution should write/output/do if given any other input.

@lyxal "from all other elements"?

lyxal

Oct 6 at 1:20, by lyxal

I didn't write it, gpt3 did, so it's open to interpretation

CMC: Given an odd prime, return (truthy/falsey) whether it is a sum of two squares

you can output two consistent values, not necessarily truthy/falsey

just have one value for "yes" and one value for "no"

so for example 3 is not a sum of two squares, but 5 = 1^2 + 2^2

CMC: Given an odd prime, return (truthy/falsey) whether it is a sum of two squares

Sequel CMC: Given a prime, return whether it can be written as x^2 + 2y^2 where x and y are integers

m90

@Fmbalbuena I first noticed that the required output was the character code of Ç, which suggested either taking enough elements off the stack to get to a Ç -- which looked unlikely -- or capturing a new string containing a Ç; one way to do that was to reuse an existing quotation-mark character in a different direction, and that worked.

i asked to ai to do the code but he does add the digits of the factorial together and convert to binary

Adám

Oh.

@Adám nope

AICMC: print the sum of the digits of input (input must be positive)

Suppose the (input must be positive) means if is negative, raise error.

@emanresuA can you express 5 as x^2+2y^2

emanresu A

Oh, I didn't see the 2.

@AaroneousMiller doesn't work if negative.

Leaky Nun

what do you mean, 1+2+3+4 is 10

Aaroneous Miller

the sum of the digits of 1234 is 10

Fmbalbuena

@AaroneousMiller but the says (input must be postive) so raise error

Aaroneous Miller

oh I interpreted (input must be positive) as (assume input is positive)
