Remember the "init" function of Haskell? It can be defined in Haskell as: init:: [a] -> [a] init [_] = [] init (x:xs) = x : init xs Formulate the appropriate Prolog rule "init(Xs,Ys)" which is true if (and only if) "Ys" is the initial part of "Xs". That is, the query "init([1,2,3,4,5],[1,2,3,4])." would evaluate to "true", or the query "init([1,2,3,4,5],Ys)." would give "Ys = [1,2,3,4]". Hint: this rule will be recursive, and will have a corresponding base case and recursive case, each analogous to the base case and recursive case, respectively, of the above Haskell function the main ‒‒‒ difference being that the Prolog rule "init(Xs,Ys)" is a predicate, not a function.
