Well... Let's try to answer (as I am a newbie :)
I found your question very easy. I am sure I am wrong so I take my camel book to see reverse
's section and I seek something which I would not have seen before.
I am not sure that reverse ($aloha)
is assumed as a LIST or a string. But my answer is "hello"
! ... and reverse ("$aloha")
will return "olleh"
