A debugger program here is having an issue: it is trying to repair a memory reallocation routine, but it keeps getting stuck in an infinite loop. In this area, there are n memory banks; each m...

Definition Given some number, x calculate the smallest number i such that 2i≥x. In other words, calculate the number of bits needed to represent x as an unsigned integer. Input Input will be an unsigned 32-bit integer. Output Output will be an unsigned integer (8-bit, 16-bit, 32-bit etc. are all ...

Quickly pour liquid nitrogen I have a container of liquid nitrogen, but nothing to measure it with. I do have some containers, whose volumes I know, and I know how much I start with. My goal is to fill any container with a given amount of liquid nitrogen, with the fewest possible pours. Important...

Symmetries of a 2d array code-golf array matrix classification Given a 2d array, what symmetries does it have? Let's only consider reflections and rotations. We can classify 2d arrays into 10 classes, according to the symmetries they have. These 10 classes correspond to the 10 subgroups of the d...

Update 2 - December 8, 2021: We’ve shipped a bunch of refinements over the last 24 hours or so. We’re going through the bugs and design requests and marking them with the proper tags. There’s a lot here, so it’ll take us a minute. We’ve done the following to address your design feedback in the ne...

Chunk Sort a List code-golf sorting Your task is to input a list of integers and chunk sort it. You may assume the input list can always be chunked into groups of 1, 2, and 3. Definition Chunk sorting (a term I made up for the purpose of this challenge) is the action of first chunking a sequence ...
