Whoa, whoa, whoa ... stop typing your program. No, I don't mean "print ABC...." I'm talking the capitals of the United States.
Specifically, print all the city/state combinations given in the following list
in any order
with your choice of delimiters (e.g., Baton Rouge`LA_Indianapolis`IN_... i...
Given a square of text representing a spiral of characters, rotate it!
The spiral starts at the center and moves counterclockwise to the outer edge
987
216
345
This translates to the string 123456789. Rotation is done to the left, so if you rotate it one position, it will be 234567891. This i...

Typesetting multidimensional labels code-golfcountingpermutations3d
In a steam-punk multidimensional world, our boss wants to affix printed index labels to each drawer in our conglomerate's multidimensional file cabinet.
The boss wants to typeset the entire label sheet as a single form, using a...
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...
Introduction
In this challenge, your task is to decide whether a given sequence of numbers can be separated into two subsequences, one of which is increasing, and the other decreasing.
As an example, consider the sequence 8 3 5 5 4 12 3.
It can be broken into two subsequences as follows:
3 5 ...
Print a Symbolic Negative of your Code
This is a variation on Print a Negative of your Code, which I enjoyed a lot! Thanks to Martin Büttner♦ - almost all of this text is his.
Let's consider the symbols to be the following printable ASCII characters (note that space is included):
!"#$%&'()*+,...
Given a list of lengths, and a string representing those lengths, do they match?
Input
Two lines of data, separated by a newline.
The first line will be a space separated list of integers, example:
3 6 1 4 6
This line describes a pattern that the second line must match.
The second line wil...
In chaos theory, the horseshoe map is an example of how chaos arises in a simple process of folding and squashing. It goes like this: take an imaginary piece of dough, fold it, and finally squash it to its original size. Chaos arises in the pattern of how the pieces of dough end up in the final a...
Imagine you got a list containing the alphabet repeated infinite times:

You start at a, your index is 0, and the should_write boolean flag is False.
Foreach character in the input, you should:
Print (or add to the return value) the n-th item of the list if ...
I don't thing the tag needs to cover all nuances.
If the main task is to write the shortest program that achieves a task, it's code golf. As long as modifications don't change the main focus, they don't change anything.
In some extreme cases, the modifiers may become the main challenge, and gol...
