[CentralOH] Python Problem for DoJo Tonight

[Travis Risner]

Hi folks,

Here is today’s problem for people who show up at the DoJo tonight.

	Implement a URL shortener with the following methods:

	shorten(URL), which shortens the URL into a six-character alphanumeric
	string, such as zLg6wl.

	restore(short), which expands the shortened string into the
	original URL. If no such shortened string exists, return null.

	Hint: What if we enter the same URL twice?

See you at the DoJo:

	Smokehouse Brewing
	1130 Dublin Road
	Columbus, OH  43215
	(614) 485-0227
