i guess i passed the first requirement to return the reversed order of the list
and believe i messed up when creating a set then add data to the set, also
something is wrong with returning the keys of the dictionary
can someone point out the error in my code and the meaning of the unittes error?
You're nearly there.
After you've called the function, anything you do to the result is not
done BY the function and will therefore not be done when called by other
code.
The unit test that calls the function will not do those things. It
expects them to already be done.
So ... what changes to your function do you think would fix that?
