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?
