Overview
Write a program that prints out simple fractal patterns given a bit pattern encoding the fractal, plus the per-generation scale factor of the fractal and number of generations.
Explanation
Here is an ASCII representation of the Sierpinski Carpet:
Generation 0:

You have a swimming pool that is filled to the brim with water. You need to empty it, but you can't think of an efficient method. So you decide to use your red solo cup. You will repeatedly fill the cup all the way and dump it outside the pool.
Challenge
How long will it take to empty the pool...
Your goal is to write a program that will print out the Laplace transform of a polynomial function f(x). The Laplace transform of f(x) is defined as the integral from 0 to infinity of f(x) e^(-sx) dx.
The standard input for the polynomial function will be
a+bx+cx^2+dx^3+...
If the coefficien...

Challenge
Write a valid program which, when just two characters in the program are changed, removed or added, completely changes the output.
The changed output must have a Levenshtein Distance of 15 or more from your original output.
The output must be non empty and finite. Your program theref...

You have N lists
A = [5, 6, 10, 15]
B = [3, 0, 7, 4]
C = [49, 59, 29]
D = [19, 29, 39]
E = [9, 15, 3, 10]
You have to combine them such that:
Two lists which have a common elements they should be next to each other. In this case answer is:
A,E,B,C,D
[5, 6, 10, 15, 9, 3, 0, 7, 4, 49, 59, 29, ...
C, LambdaBeta
Description
Turn main(a,_) into main(_).
Code
main(_){puts(_*_-1||_*_*_-1||_*_*_*_-1?"Expected Output":"?");}
Find the shortest way to generate a random number between 0-9 without repeating the last generated number. Here is an example written in javascript.
var n=t=0;
while(n==t){
t=Math.floor(Math.random()*9);
}
n=t;
I don't know if it is possible, but it would be interesting if there is a soluti...

If you dare, try it online.
There's also this ASCII-only version:

The spaces should actually be a tabulator.

Is a picture worth a thousand words?
There is an old saying that goes "A picture is worth a thousand words".
For us programmers, pictures and words are actually quantifiable in bytes.
(A word is worth 8 bytes on a standard 64-bit system, a thousand words is worth 8000 bytes, and an image is wort...
