Hi
mapM_ putStrLn (hanoi 2) -- outputs each move in a new line putStrLn (unlines (hanoi 2)) -- same as previous line
putStr (unlines (hanoi 2)) is what you want. Unlines puts a trailing new line at the end of every line, including the final one. putStrLn puts an additional trailing new line, so you get 2 at the end. mapM_ putStrLn == putStr . unlines Thanks Neil
