String Mingling

  • nitinpatel278 + 1 comment

    Using recursion: 

    mingle "" "" = ""
mingle p q   = (head p) : (head q) : mingle (tail p) (tail q)

main = do
  p <- getLine
  q <- getLine
  putStrLn $ mingle p q

      did this pass? Without tail recursion, common-lisp fails at 9 and 10 (heap exhausted). And even with tail recursion, it fails at 10 because of the time limit, so I had to use a map, and no recursion, even though this is in the "recursion" section!!

        Haskell solution did pass all the test cases. I don't know much about tail recursion to comment on that.
