Document Summary
Circle the nal result of simplifying the following ocaml expressions, or in nite loop if there is no nal answer. Note: the de nition of the transform function appears on page 11. Also recall that the @ operator appends lists together: let rec f (x :int) (m : int list) : bool = begin match m with. | [] :: u -> 0 :: h u. | (x :: t) :: u -> 1 :: h (t :: u) end in h [[1];[];[1;2]: [1;0;0;1;1;0, [1;1;2, [1;0;1;1, [[1];[];[1;1], in nite loop. For each ocaml value below, ll in the blank where the type annotation could go or write ill typed if there is a type error on that line. Your answer should be the most speci c type possible, i. e. int list instead of "a list. Some of these expressions refer to values speci ed by the set interface from homework 3.
