axiomsofchoice / binarysearch.py

Created April 18, 2011 15:29

An attempt at Jon Bently's binary search algorithm challenge from his book "Programming Pearls"

	"""
	An implementation of binary search, based on the challanges in the following blog posts:

	http://googleresearch.blogspot.com/2006/06/extra-extra-read-all-about-it-nearly.html
	http://reprog.wordpress.com/2010/04/19/are-you-one-of-the-10-percent/
	http://www.solipsys.co.uk/new/BinarySearchReconsidered.html?tw

	This was not my first attempt however, there was a broken version (of course)
	that I wrote prior to running it for the first time. Sadly I didn't take a
	snapshot before I fixed it but the bug was fairly major; although I'd worked
