lastPositionOf:
Find the position of the last occurrence of an element inside a list
(quite difficult): Create the function lastPositionOf which will be given an element and a list, and will return the position of the last occurrence of the element inside the list. It will return 0 if the element is not found. NOTE: YOU ARE ALLOWED TO CREATE NO MORE THAN ONE HELPER FUNCTION! (lastPositionOf 'a '(a b a)) ; -> 3 (lastPositionOf 'a '(b c d)) ; -> 0
