Cops and Robbers: Text Transformations
Cops' challenge
The cops must write a fully deterministic program that reads input from STDIN and writes output to STDOUT as its only side effects. The mapping from strings to strings performed by this program will be called f.

Cops' challenge: Design a programming language that appears to be unusable for programming, but admits computation (or at least completion of the task) through some non-obvious mechanism.

Pip
A golfing language created by DLosc (me), first published in April 2015.
Pip is a procedural language with infix operators. It is designed to be terse but still familiar to those who know C-like languages. For instance, it shouldn't be too difficult to see why this code:
Fi1,6Pi
prints t...
Using a non-free language on a Cops and Robbers challenge
Most (currently all) cops and robbers challenges consist of two parts:
A cop submission, where a user posts some secret property of a program, such as its output, a scrambled version of the code, etc.
Then, other users, the robbers, try...

In various Super Mario games green and red Koopa Troopa shells can slide frictionlessly on flat surfaces and destroy brick blocks that are in their way. When a shell hits a brick block the block breaks, turning it into empty space, and the Koopa shell reverses direction. As an example, watch the ...
I have recently noticed something odd that I don't like very much:
So why am I getting a train upon running ls? And how can I stop this and make it behave normally? Is this an Easter Egg that I have discovered? I am running Ubuntu GNOME 15.04.
Information Update:
Running which ls gets me the...
Acronyms can really obviously narrow your message sensors.
code-golf
Because of this, you need a better way of working out if a phrase is an acronym of a word. You also think it would be worthwhile to see if the phrase and word in question are recursive acronyms.
Your task:
Given a word and ...
Hi I have a sample string . I need to find if the characters of the sample string is in the same order in the text string

Home improvement for the Minotaur
The cretan labyrinth is quite easy to draw. Just start with a symmetric shape (here in red). Let us call all the endpoints of those lines 'nodes'. Then you begin drawing the arches (black): The first one alway begins in the top middle node and connects to the n...
*Overwrit*labels string code-golf
If you've ever tried adding labels to a really dense plot, then you'll realise that sometimes labels will overlap one another, making them hard to read. We're going to do something similar but in 1D.
Input will be a sequence of (label, x-coordinate) pairs, and ...

I've been here a few months now, and I've noticed the ridiculous amount of languages used and exploited in code-golf. However, documentation can sometimes be lax, and understanding can sometimes be limited, but...
Try to write some code in your language and make it not satisfying our criteria of being a programming language any more.
A language satisfies our criteria (simplified version for this challenge) of being a programming language if:
It can read user input representing tuples of positive integer...
Java
class D {
static {
System.out.close();
}
public static void main(String[] a) {}
}
You can insert your code pretty much anywhere; it won't matter. This closes STDOUT, which makes Java no longer a programming language since it does not have a transformational model.
Golfing Golf
Golfing is hard. Even the best of us miss stuff that can shave off a few bytes. Inspired by this question, I decided what better way to improve our golfing than to write programs to do it for us?
The Challenge
You must write a program (or function, it doesn't matter) that, when gi...
Your job, should you choose to not refuse it, is to write a program that will "golf" a piece of given code in your language of choice.
Basic functionality:
Remove extraneous whitespace
Remove comments
'Advanced' functionality:
Combine declarations (int x; int y; int z; to int x, y, z;)
