// Daniel Lemire in this article
// https://lemire.me/blog/2013/12/26/fastest-way-to-compute-the-greatest-common-divisor/
// presented benchmark comparisons of different implementations of Stein's (binary) gcd algorithm.
// The wikipedia (iterative) implementation of the algorithm was noted to be very inefficient.
// Lemire presented benchmarked comparisons of various implementations, original code below.
// https://github.com/lemire/Code-used-on-Daniel-Lemire-s-blog/blob/master/2013/12/26/gcd.cpp
// I have modified the output to make it explicit and clear, modified the code in some functions
// to make them easier to follow and standardized variable names, and added the Ruby implementation.
// I also ordered the ouput to show fastest to slowest.
// The results: gcdwikipedia7fast32 is fastest by far; the implementation shown in widipedia is slowest.
