Suppose we define an infinite matrix M, on N^2 -> {0, 1} (where N starts from 1 instead of 0) in this manner:
M(1, 1) = 0.

For every y > 1, M(1, y) = the yth term in the Thue-Morse sequence.
For every x, y > 1, M(x, y) = M(x, y-1) + M(x-1, y) mod 2.

Inspired by this question on SO, your task is to produce a program that is valid in (at least) two major versions of your chosen language that produce different output.
Rules
Any language that has more than one major version can be used.
For the purposes of this challenge, I would suggest a "major version" is where ... |
I know there is an (old) thread similar to this (here), but I'd like to reboot it with some modifications.
The goal: generate a random-looking maze using an algorithm of your choice, then output the maze graphically (printing counts).
The width and height are determined by you.
There should be at least one path from a... |
Task:
Remove all duplicates from one list of integers. A list is simply a sequence of connected values that allows the same values to be stored at different positions in this sequence.
If an item was found to be the same value as another item in this list, keep the first occurence of the item and remove the second (thi... |
The challenge is to, given a list of points, sort in a way that, when they are connected in this order, they never intersect.
Input format (read from stdin):
X Y
1 2
3 4
5 6
...
Output should be the same as input, but sorted.
Rules:
You can start from any point.
The last point must be same as first one, making a clos... |
You are given a directed graph in an adjacency dictionary format. This can be whatever format is most natural for your language. For instance, in python, this would be a dictionary with keys of nodes and values which are lists of nodes which that node has an edge to. For instance:
G={1: [2, 3], 2: [3], 3: [1], 4:[2]}

As I'm sure many of you know, synonyms can range from very similar to not-so-similar-but-I-can-see-how-it's-similar. It's common for dictionaries to use "See also" to denote occurrences of words that have especially good synonyms. Thesauruses (Thesauri?), on the other hand, list every word that is remotely close in def... |

Given a string where the first line contains spaces and one period (., the "ball"), followed by lines containing spaces, forward slashes (/), and backslashes (\), determine what column the ball will land in after falling from its starting position. Each / moves it to the left by 1 column and each \ moves it to the righ... |
