impressive indeed @Phil15: Was this your first iteration?

It seems to be my only published solution, so I think it is. I think it's straightforward, just had to think about `(s,s-r),(s-r,0),(0,r),(r,s)` (and test it).

Simple but logical. Nice solution to use divmod to get the side of the square and use the 4 possible calculations in a tuple.

Very easy to read without multiple if/else statements

Great and short solution. I think, it can be in cathegory "Speed", because all calculations reduced to one divmod. Really smart and educational.

Different kind of sets
