Factorial

This repository contains the factorial function:

f(0) = 1
f(n) = n * f(n - 1), n > 0

coded with a number of different algorithms/implementations in various languages. The purpose is not to provide Factorial as a Service (FaaS), but it to investigate data-driven testing (both example based and property based) in the various languages.

See Also

Rosetta Code is possibly the premier location of examples of coding. For factorial see http://rosettacode.org/wiki/Factorial They are though concerned only with the code of the algorithm, the point of this repository is as much the tests as the algorithms.
