This challenge revolves around getting the functionality of a single output function and reimplementing it to another language. Syntax doesn't matter, only functionality.

Suppose a challenger submits a code-golf challenge to do a particular task, together with test inputs. (That is, they've determined that, in order to be convinced that the code in an answer correctly performs that task, it must do the right thing when given each of those test inputs.) How should ...

Is this an L-shape? code-golf decision-problem binary-matrix polyomino Background An L-shape is defined as a polyomino which can be made by extending two rectangular legs in orthogonal directions from a square (called a pivot). The size of the square should be at least 1, and the lengths of the t...

I spent yesterday evening to challenge myself to program the smallest playable version of one of the most well-known games out there: Tic Tac Toe. Mainly for fun, and to learn a bit more about Python in general. Some requirements for the challenge: A reasonable user interface (e.g. input moves a...

Robber Thread here The Challenge Choose any numeric* formula, algorithm, or code challenge. Implement it in such a way that the math is correct, but at least one answer is wildly** wrong due to some defect in how computers/programs operate, e.g. floating point errors, uninitialized/corrupted memo...

Challenge The cops created code challenges which result in certain wildly incorrect answers despite correct math. Choose an uncracked, not safe formula from the cop thread. Your task is to find an incorrect answer and describe its underlying cause. The challenge author has the responsibility to c...

Implement a zipwith function zipwith is a functional construct that takes three arguments: one binary function, two lists of the same length, and returns a single list where each element is constructed by applying the binary function to each pair of elements from the two lists: zipwith (a+b) [1,2...
