It's good to admit that looking at the code has ceased to help :-)

So, try a different approach. Without using the code, can you describe
your algorithm? Make a pseudo-code description of how you expect to
transform the input to the output.

For example, I might describe the algorithm for reversing a text
string::

    * Given a text string named ‘input_text’
    * Set the output, named ‘output_text’, to the value "".
    * Set the index (named ‘index’) to the character length of ‘input_text’.
    * While ‘index’ is greater than 0:
      * Subtract 1 from ‘index’.
      * Get the character at index ‘index’ of ‘input_text’, assign the
        name ‘input_char’ to that character.
      * Append ‘input_char’ to ‘output_text’.
    * Return the value of ‘output_text’.

Can you describe your algorithm that way, so we can see what is your
intention for the code?
