Inspiration Conway's Game of Life is a well known cellular automaton "played" on an infinite grid, filled with cells that are either alive or dead. Once given an initial state, the board evolves according to rules indefinitely. Those rules are: Any live cell with 2 or 3 living neighbours (the 8 ...

Remaking Kernel code-golf I made a program as a final project in the main CS50 Harvard course, and it was named Kernel, written in C alsongside CS50's library. Functions It has 7 functions: 4 main (talk, count, calculate, build) and 3 advice functions (error, feedback, help). What each function d...

Background A polyomino of size \$n\$ is a contiguous shape made from joining \$n\$ unit squares side by side. A domino is a size-2 polyomino. A polydomino of size \$2n\$ is defined as a polyomino of size \$2n\$ which can be tiled with \$n\$ dominoes. The following are some examples of polydominoe...

For each integer n, 0 or higher, output the lowest power of 2 that has two identical sub-strings of n digits in decimal, and the two indices where the digit sub-strings start (0-based). n      Output      Proof (don't output this) 0 => 0 [0 1]        (_1 & 1_) 1 => 16 [0 4]     ...

Write some statement(s) which will count the number of ones in an unsigned sixteen-bit integer. For example, if the input is 1337, then the result is 6 because 1337 as a sixteen bit binary number is 0000010100111001, which contains six ones.

When a number is shown on a calculator, it's possible to consider what various transformations of that number would look like. For example, on a seven-segment display, 2 is shown like this: And when flipped horizontally it looks like this: As such, the mirror image of 2 is 5. The task in t...

There are quite a few accumulator-based programming languages featured in challenges across the site, but it's a little tiring to have to write almost identical code for each one. So in this challenge you will write a program which can generate interpreters from an input. How does this work? Let ...

Life: Nothing + Nothing = Glider (WIP) Gauging Interest game-of-life code-challenge Your task is to create two patterns which will eventually result in an empty board when by themselves, but when combined in a certain non-overlapping arrangement, eventually spawn a single glider and nothing else...

Introduction The Nineteenth Byte is CGCC's official chatroom (go check it out!). Its name is a play on the nineteenth hole, and it also refers to golf, which is appropriate for CGCC's chatroom's name. The name is also precisely \$19\$ bytes long, as its name states. Challenge Your task is to writ...

What's my TIO uniqueness? Try it online! currently has 680 listed languages, all of which are searchable. For most of those languages, when searching for it, you don't have to enter the entire string. For example, entering lega results in just 05AB1E (legacy) appearing, and entering d+ results in...

Given a pattern of squares on a grid, determine if it is possible to create that pattern with non-overlapping dominoes. In case you are not familiar, a domino is a rectangular shape created by joining exactly two squares at their edges. Examples For the pattern on the left, O represents an occupi...

ROT47(code) ROT13 is a Caesar cipher where every letter is replaced by the 13th letter that follows it in the alphabet. Every letter and its counterpart: |a|b|c|d|e|f|g|h|i|j|k|l|m|n|o|p|q|r|s|t|u|v|w|x|y|z| |--|--|--|--|--|--|--|--|--|--|--|--|--|--|--|--|--|--|--|--|--|--|--|--|--|--| |n|o|p|q|...

There are currently 13 questions tagged with faq-proposed, the "staging ground" for posts before they become official faq posts and are added to the FAQ. faq-proposed is not intended to be a permanent tag, more of a placeholder, yet of these 13 questions, the most active (in terms of tag edits) w...

200 – 500 rep for outgolfing my Fibonacci regex If you can write an ECMAScript (pre-2018, no lookbehind) regex that matches exactly the same set within the domain ^x*$ as my 161 byte regex, i.e. all nonnegative Fibonacci numbers in unary, I will award at minimum a 200 rep bounty. If it's a really...

Leave a wake of dead cells behind you Conway's Game of Life is a well known cellular automaton "played" on an infinite grid, filled with cells that are either alive or dead. Once given an initial state, the board evolves according to rules indefinitely. Those rules are: Any live cell with 2 or 3...
