For Problems 3 and 4, the Node class is declared as: class Node { int value; Node next; // constructors } Implement the method int numberPositive(Node head) that counts the numbe positive integers in a linked list of integers recursively. Assume the linked list is reference 3. head. Implement the method Node search (Node head, int key) that returns the reference to the node with the value key in a linked list of distinct integers recursively. 4. Assume the linked list is reference by head. The method returns null if the search fails.

Define a function compress : lists(T) → lists(T) that accepts a list argument (of some generic type T) and returns a list without any subsequent redundancies, e.g. compress(⟨a, a, b, b, b, c, c, a, b⟩) = ⟨a, b, c, a, b⟩ 1. Transform the definition into a computable function.2. Define f recursively.3. Unfold your definition for compress(⟨a, a, b, b, c, a⟩).4. (PROGRAMMING) Please map your definition into a Common LISP function. Place your code in file compress.lisp. The code should behave as follows: > (compress ’(a a a b c d d e))(A B C D E)> (compress ’())NIL> (compress ’(a b c c c a))(A B C A)> (compress ’(a a b b c c c c a b b))(A B C A B)
