Re: [Haskell-cafe] All binary strings of a given length

Not the most efficient, but easy to understand: genbin 0 = [] genbin 1 = ["0", "1"] genbin i = map ('0' :) x ++ map ('1' :) x where x = genbin $ i - 1 On Fri, Oct 15, 2010 at 2:21 PM, rgowka1 <rgowka1@gmail.com> wrote:

Hi -

How can I generate all binary string of a given length? The type signature would something like -

genbin :: Int -> [String]

For example genbin 2 would give ["00","11","01","10"] and genbin 3 would give ["000","001","010","011","100","101","110","111"] etc..
