Implement Uiua's 'tuples' function
In the programming language Uiua, there is a higher-order function called tuples which is a generalization of getting the permutations or combinations of an array. Tuples takes a list \$ a \$, a sample size \$ r \$, and a function \$ f \$ taking two numbers repr...
COBOL is a high-level, compiled programming language designed for business applications, readability, and long-term maintainability. It emphasizes verbose syntax, English-like readability, and robust support for data processing, file handling, and business logic. COBOL's structure is divided into...
What are some general tips you have for golfing in Bespoke? I want answers that are specific to Bespoke (e.g. don't just say "remove comments"). One tip per answer.

The shortest NP-complete problem
Find an NP-complete problem over all ASCII strings, and present a solver for the problem in the programming language of your choice.
This is a code-golf; the solver with the fewest bytes wins.
Your submission must present a proof that the problem in question is in...
Find duplicates in a given string
code-golfstring
Challenge
Given a string of any length, determine if there are any duplicate characters in the string.
Rules
Standard I/O methods are permitted. Standard loopholes are forbidden.
This is code-golf, so shortest solution in bytes wins!
Examples
"abcdef
Given an unsorted list of unique, positive integers, output the shortest list of the longest possible ranges of sequential integers.
INPUT
An unsorted list of unique, positive integers
e.g. 9 13 3 11 8 4 10 15
Input can be taken from any one of the following:
stdin
command-line arguments
...
Count collisions in a python dictionary
hashing python code-golf
Task
Given a list of integers as input, simulate Python's dictionary insertion process and count the total number of collisions that would occur. The process works as follows:
Start with a hash table of size 8
For each number in th...

Position 9 queens and least obstacles on an 8×8 chessboard so that no two queens threaten each other.
There's more than one solution. Output all of them. Shortest code in each language wins.
Uiua is a stack-based array programming language, and with the great power of a stack comes the great responsibility of having to manage it. In this task you will take on the role of the Uiua interpreter for a small subset of the language concerning the rearranging of values on the stack.

I saw the following problem on MathsSE:
You try to do something and your probability of success is \$p\$. If you fail, you try again, but the probability of success falls down to \$p^2\$. If you fail again, you try again, but the probability of success is now down to \$p^3\$. If you fail, you ke...

Q&A on metas
I feel the Q&A format is just inherently bad for meta sites. I also want to say that Q&A does not need to be completely gone, but metas can at least be diversified with the type of content. Or maybe we throw out Q&A and adopt another model.
In general, Q&A seems antithetical to metas...
The task is to compute the convolution of an array with itself as quickly as possible. The array will contain 80-bit extended precision long doubles and I will specify how the array is to be created. In order to get a good range, the values will be sampled on a log scale and then scaled back up ...

This challenge is about probing the limits of an LLM's reasoning skills. The basic idea is to create short DeepSeek prompts that produce long bodies of reasoning text and an objectively incorrect answer. More precisely:
