The function assocList(Isti, Ist2) returns the association list of Ist1 and 1st2. For example, for Isti - L'a, 'b', 'c'] and 1st2 - [1,2,3], the returned association list is [('a', 1), ('b', 2), ('c', 3)]. It is assumed that the two given lists have the same length. Implement the function of the specification: static List> assocList (LinkedList 1st1, LinkedList 1st2); where the class Pair is defined as follows: class Pair{ public U first; public V second; public Pair(U first, V second) { this.first = first; this second - second; 3
