The Twelve Days of Christmas Kata
The Twelve Days of Christmas Kata
What's the SMALLEST (line count) program that can produce the classic Christmas song lyrics? With just a bit of tweeking I got it down to 117 lines... I'm sure you can do better.
Go give it a try - Cyber Dojo
The Cyber Dojo (just became my favorite tool) has the lyrics in a readme.txt file for you when you select the Twelve Days Kata from it's library of programming exercises. Just to let you know the lyrics are 113 lines long...
But the exercise is not to write dense code - like I did to get down to 117... but to start refactoring the redundant lines of the code - into I would guess... loops inside of loops... inside... it's loops all the way down.
