Live coding of Ruby Quiz 7 - Arithmetic Puzzle "Countdown"
Unscripted, unedited, (uncut) - Haskell Uncut

You can find the code of this video at: https://github.com/codinguncut/Countdown
The description of the task: http://www.rubyquiz.com/quiz7.html

source 100 5 5 2 6 8, target 522. result: (5*100)+((5+6)*2) = 522

It took me so much longer to implement this than I had hoped.
In the interest of making it watchable I have (against my explicit promise) cut out four 5-minute sections that proved to be cul-de-sacs. They are of course annotated.
