The Python recursive example isn't testing that the string is a palindrome. It seems to actually be a test for whether the object tested supports len() and slicing. [[User:Drea|Drea]] 16:56, 5 December 2008 (UTC) |

Haskell recursive solution note
I suppose the Haskell recursive code can be written a lot better, but I don't know how. --ShinTakezou 14:08, 5 December 2008 (UTC)
- Does this look better to you?
is_palindrome_r x | length x <= 1 = True
| head x == last x = is_palindrome_r . tail. init $ x
| otherwise = False
