Haskell : QuickSort in 2 Lines

As an aside to the series of blogs on sorting and in an effort to ensure you that this is not a C++ only blog here's how you can express the quick sort algorithm in haskell

qsort []     = []
qsort (x:xs) = qsort (filter (< x) xs) ++ [x]
               ++ qsort (filter (>= x) xs)

Compare this to the C example below! Haskell is a high-level, functional programming language. It is definitely worth a closer look, even if you don't use it to develop anything it will offer a different mindset that may help you approach and solve problems from a different angle.
