Because the compiler won't catch if the parameters change. Work with the compiler! #fivelinesofcode

This table cloth trick is a good metaphor for refactoring, since we are changing the underlying structure (the cloth), without changing functionality (the tableware).
It also illustrates the difference between taking small and big refactoring steps.

A while ago I designed a new type of sudoku.
Two sudokus are entangled and have to be solved at once. In the two grids only the digit 9 align, thus there will be two numbers in every cell, except if there is a 9. The cages are just for aesthetics.

Sometimes functional, sometimes object oriented.
Sometimes practical, sometimes silly.
Always code!

Like many others, I also think this calls for recursion. We can take advantage of the fact that partitioning an even number results in two numbers with the same parity. In the base case (x<10) we can simply use isOdd; implemented in the obvious way.
