Let me know if this task has already been posed. I haven't found it when I looked.
Input
master sequence \$\ X = x_1\dots x_n\$: sequence of characters, eg. \$\rm international\$
"subsequence" \$\ Y = y_1\dots y_m\$: sequence of characters, eg. \$\rm intl\$

Good evening everyone,
Preamble
The aim of the game is to find the combination of the safe.
The combination is informed by yourself into the constant COMBINATION.
Rules
You have to use the combinations contained into the array ALLOW_COMBINATIONS
Your combination has to be 32 elements long.

Create a program that outputs Hello, World!
The winner is the source code that is the biggest, subject to the constraint that it is irreducible
For the sake of this challenge irreducible means there does not exist a set of characters that, when removed, would result in a program that also outpu...
Longest Prime Sums
There are special sets S of primes such that \$\sum\limits_{p\in S}\frac1{p-1}=1\$.
Input: None
Output: A set of primes which satisfies the conditions above.
This challenge is a code-challenge, where your score is the size of the set you output.

Get to my destination code-golf path-finding
Given the speed of the car, the length of the road, and the position of my destination, output the fewest possible steps I need to get to my destination.
How does the car move?
This car that I rode in the morning has a weird feature: after the drive...

I am trying to search math.se for an answer but I have forgotten exactly who wrote it. Is it possible to search for all answers with the tag combinatorics and where the answerer's name includes the string kevin?
Introduction
An elementary cellular automaton is a cellular automaton that is 1-dimensional and has 2 states, 1 and 0. These cellular automata are categorized based on a simple code: the Wolfram code, invented by Stephen Wolfram (yes, the Wolfram | Alpha guy). It works like this:
First, you th...
Introduction
Big 2 is a card game popular in East Asia and South East Asia, in which 4 players are dealt 13 cards each (ie, an equal division of a standard deck without jokers). The goal is to empty your hand before any of the other players. Players take turns playing combinations of a Big 2 sub...
Coding Question
You are given a hexadecimal-encoded string that has been XOR'd against a single char.
Decrypt the message.
For example, given the string:

I'm trying to make some sounds for a GUI, and exploring what other people have done makes me realize how much effort really goes into things like phone sounds
@dzaima I think for [[/]], it's the same as a dropper when both sides are pushed. When duplexed packets drop onto them, it's the [/] side that's pushed to the side
Google shows a definition of show to be a spectacle or display, typically an impressive one, which doesn't necessarily imply sight or vision (probably evolved from TV show, yeah)
@DJMcMayhem Doesn't appear to have evolved from TV show. books.google.com/ngrams/… shows radio show appeared before television show and even dropped in popularity soon after
i'm beginning to think your interpreter has some strange timing things (or that mine doesn't) - my hello world outputs the same characters in your interpreter, but in a completely different order..
Oops, unclear, each packet moves one unit per cycle. It uses a six for loops per cycle
1. Move all packets up/down 2. Process up/down triggers and store to "to be pushed" or drop immediately 3. Process push triggers from previous cycle and store to "to be pushed" or drop immediately 4. Push all packets in "to be pushed" 5. Pull and store to next cycle's "to be pushed"
gif of the result of my processing style (here's hoping imgur isn't blocked too)
(now that i think of it, i should say that my model is actually 2 steps - one to collect individual actions from each units, and the second to actually apply them)
@dzaima um, i counted a bunch of trailing ..\n..\n…s, it's actually 638 bytes.. (and there's still some golfing potential, but i'm gonna stay within my interpreter)

A spin-off of a rip-off of a rip-off of a rip-off of a rip-off. Go upvote those!
Your task, if you accept it, is to write a program/function that outputs/returns its input/argument. The tricky part is that if I left shift your source code, the output must be left shifted too. Likewise,...
@RedwolfPrograms oooh. that probably opens up a bunch of possibilities (including my original idea of dropping all the numbers already at their correct places and outputting all at the bottom)
Sandbox
Background (not necessary for the challenge)
A standard number theory result using the pigeonhole principle is the fact that given any natural number k, there is a Fibonacci number that is a multiple of k.
We can see this by considering modular pairs (F(n-1) % k, F(n) % k), and noting ...
@RedwolfPrograms to time things properly. some might be removable, but iirc then i started getting multiple outputs in the same frame which i've yet to decide the behavor of
@RedwolfPrograms that's probably what happens in mine too, but it's asymetric which is ugly. I've thought of making multiple input requests in the same frame just give the same input multiple times for example.
Oh, okay. I'm sure there's a point where it's less bytes to generate the number than use increments, but it's probably way beyond the limits of ASCII codepoints...
