The question is not clear enough

    When I first working on this question, I just convert it to word array, reverse it, then join them together, it gives me errors for the case ' ' should be '', not ' '. I think the question is not making it clear that you should trim the white spaces.
    I believe what it actually wants is ' this is a tree ', should be 'tree a is this', should trim the extra space in between. This should be decalred more clear in the question.
