Your task is simple: given two integers a and b, output ∏[a,b]; that is, the product of the range between a and b. You may take a and b in any reasonable format, whether that be arguments to a function, a list input, STDIN, et cetera. You may output in any reasonable format, such as a return valu...

Background PICASCII is a neat tool that converts images into ASCII art. It achieves different degrees of brightness by using the following ten ASCII characters: @#+';:,.` We'll say that these charxels (character elements) have brightnesses from 1 (at-sign) to 10 (space). Below, you can see...

Monday numbers, as defined by Gamow in this question over on Puzzling, are positive integers N with the following three properties: The decimal representation of N does not contain the digit 0 The decimal representation of N does not contain any digit twice N is divisible by every digit D that ...

Given an image that has only black and white pixels and an (x,y) location that's a white pixel, color the white pixels based on their minimal Manhattan distance from (x,y) in a path that only involves traversing other white pixels. The hue of the colored pixels must be proportional to their dist...

Lenguage, 0 Output is in unary, since Lenguage/Brainfuck has no sane way of printing integers in base 10. The actual source code contains 223605599678244445677917099137136598260445583049693744517915142254904733730402123327574095535587581070850157973202762135155027962550827178026323991235020...

Brainfuck, 120,148 bytes This answer is now non-competitive. This was before the rules were changed, and this has absolutely no hope of winning as code-golf. Brainfuck code to output hex value of image. Very, very, long. Here is a pastebin link, and the first couple lines. https://paste.ee/p...
