Introduction
In this challenge, we will simulate a certain probabilistic cellular automaton using very bad pseudorandom numbers.
The cellular automaton is defined on binary strings by the following local rule.
Suppose that the left neighbor of a cell and the cell itself have states a and b.
If...

The Cake Cutting Contest
king-of-the-hill
It's my 17th birthday and you're invited to my party!
And as always at parties, there will be cake.
One cake...
And you need as much of it as possible.
As this is a fair party, each of us will say how much of my cake we want and the person who said...
Fill the grid!
A challenge with simple rules but non-trivial algorithms. :-)
Task
Take input in the form of space-separated integers:
N A B S
Where N is the side length of a 2D square matrix filled with unique numbers (integers) between A and B inclusive. For each row and column in this mat...
I define the following operators:
Manhattan Addition a +M b, for single-digit numbers, is the result of concatenating b onto a. So, a +M b = 10a + b. Therefore, the general operator +M is defined as thus:
a +M b = 10a + b
Manhattan Subtraction a –M b, for single-digit numbers, is the result of...
