Problem 3 (25 points) Write the code for the function getIntersection below, that given two sorted linked lists returns a linked list that is an intersection of them. Assume that these linked lists are implemented by the class IntList with the interface from Problem 2 IntList& getIntersection(IntList& intListl, IntList& intList2) IITODO: you code here Estimate the big-O complexity of your implementation
