Non-associative operators (for example the subtraction-operator) often are either left- or right associative, such that one has to write less parentheses. Consider for example the following...
Write a program that is a polyglot is 2 programming languages that converts an input integer, from 0 to 100 inclusive, to words, each in a different human language.
For example, given the input "3":
when running your program as Python code, it would output "three" (English)
when running your ...

I've seen many challenges get marked as duplicates on this stack. Most I see as fair, some, not so much.
What qualifies as a duplicate question?
Consider challenges where:
Entries from a will be valid for b , and entries from b will be valid for a
Entries from a will be valid for b , but en...
With the traditional caveat that extending built-in prototypes is not necessarily the best idea, and that it's something to be done with caution, you can get the generator function prototype with
const genproto = Object.getPrototypeOf(function*(){});
With that you could add a filter() capabili...
I posted this on the math exchange, and was told that maybe it would fit better here.
Given an arbitrary point on the triangle pictured below, what is the "best" way to determine which of the 60 sub triangles it lies within? Suppose I have the coordinates for all sub-triangle vertices.
"Best" ...
