Background An L-shape is defined as a polyomino which can be made by extending two rectangular legs in orthogonal directions from a full square (called a pivot). The size of the square should be at least 1, and the lengths of the two legs should also be at least 1. These are some examples of L-sh...

Here is the problem, for which I can only think of an iterative solution and have not found a closed formula. You need to paint a house with R rooms. For each room there are four walls and one ceiling, which all have the same dimensions and need C coats of paint. You can't paint the next coat ...

Quines, error quines, hello world, polyglots, oh my! Introduction A quine is a program that outputs its own source code. For example, a well-known Python quine is _="_=%r;print(_%%_,end='')";print(_%_,end=''). Running it outputs _="_=%r;print(_%%_,end='')";print(_%_,end=''), therefore it is a val...

Peano numbers represent nonnegative integers as zero or successors of other Peano numbers. For example, 1 would be represented as Succ(Zero) and 3 would be Succ(Succ(Succ(Zero))). Task Implement the following operations on Peano numbers, at compile time: Addition Subtraction - You will never be ...
