A live coding session demonstrating how to implement a solver for the Countdown arithmetic puzzle in Haskell.
Live coding of Ruby Quiz 7 - Arithmetic Puzzle "Countdown" Unscripted, unedited, (uncut) - Haskell Uncut Read more at my blog post: codinguncut.com/arithmetic-puzzle/ You can find the code of this video at: github.com/codinguncut/Countdown The description of the task: 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.
