A theorem in this paper1 states that every integral n-by-n matrix M over the integers with trace M = 0 is a commutator, that means there are two integral matrices A,B of the same size as M such that M = AB - BA. Challenge Given an integral matrix M with trace M = 0 find some integral matrices A...

I have a non-challenge, bitwise-gymnastics question that I am looking for a home for. Would this be on topic here? Per some requirements, I am trying to pack three data points into 16-bits for the fourth position of an Assembly's File Version (in .NET, the fourth position of a version number ca...

I'm having a hard time in my code. The question may be silly but for me it's pretty hard because I'm starting with python I have this selenium python code. I just simply need to return a JSON if one goes wrong with the robot search. robo.py import json from selenium import webdriver from selen...

With challenges like Output with the same length as the code and Create output twice the length of the code, I thought of a separate, but similar challenge. The task is to produce an output. It can either be a string, a list of characters, or whatever is the default output format of your progra...

Levenshtein Neighbours Every square number has at least 1 different square number with which their Levenshtein distance is exactly 1.* For a given square \$x\$, each square that meets this condition is called a Levenshtein neighbour of \$x\$. For example, \$36\$ is a Levenshtein neighbour of \$1...

I mainly need help with scoring as I want to encourage use of esolangs. I also would like to know how to improve the answer-ability of this question in languages that don't specifically have defined functions Church booleans A church boolean is a function that returns x for true and y for fa...
