Thanks Felipe Lessa for shortening the code :) and everyone for advice.
I have recently started learning haskell from the book
Learnyouahaskell - www.learnyouahaskell.com - I am done with the book except
for Bytestreams and randomness. Was trying to put my haskell skills to use
on the problems of this kind. My aim is to understand and practice haskell
and not WIN these code golf competitions! . So, please suggest me what are
the other books i can read ( and work through :) ), in general any good open
source projects to involve in, etc.. basically any advices to improve as a
Thanks in advance.
