The FizzBuzz problem is a simple coding demonstration to write an application in any language that counts from 1 to 100:

Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”.

I found the following on Stackprinter (deleted Stackoverflow questions) by  â€śysth”; probably the best example of wicked-cool code obsfucation, ever.
