$$Add a return Statement

In the backwards technique, we work from the end. We know from the specification that second

$\_$

in

$\_$

list is a fruitful function, so the last thing to do is to return the result. Add a return statement to the body of second

$\_$

in

$\_$

list. Pick a variable name to return

$($

other than s

$,$

$$which does not contain the answer

$)$

$.$

$$It can be anything you want, though it is standard to name the return variable result. Do not add any other lines of code to your function body.

Now that you have added this line of code, it is time to run the test script that we have provided

$($

always test after you write new code

$)$

$.$

Run the Test Script

Do that, then copy and paste the output below.
