Thanks Felipe Lessa for shortening the code :) and everyone for advice. <br><br>I have recently started learning haskell from the book <br>Learnyouahaskell - <a href="http://www.learnyouahaskell.com">www.learnyouahaskell.com</a> - 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 haskell programmer.<br>
<br>Thanks in advance.<br><br><br><div class="gmail_quote">On Wed, Jun 30, 2010 at 9:50 AM, Lyndon Maydwell <span dir="ltr"><<a href="mailto:maydwell@gmail.com">maydwell@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
I agree. If you're aiming for really terse code, have a look at the<br>
J/K languages. These seem to win most golf-shootout type competitions.<br>
Haskell is more focused on expressiveness and abstraction.<br>
