Why when input is " ", expected is ""?

  • 35

    I got "Wrong answer" as:
    Input: " "
    Output: " "
    Expected: ""

    I think for input " ", the output is supposed to be " " when reversing the string, am I missing something here?

    According to the clarification, result should not contain leading or ending spaces. Therefore, when given word list is none, we might expect empty string.
