% Get last element from the list
% Explanation:
% Last element of list containing one element is the element
% Recursively call my_last on TAIL of the list, in rule head notice the underscore
% sign. We put it there because our rule body does not need to contain named
% reference to the list head - in other words, we don't care about it.
my_last(X, [X]).
my_last(X, [_|T]) :- my_last(X, T).
