Problem: Write a method named intersect that accepts references to two sorted ArrayList of integers as parameters and returns a new list that contains only the elements that are found in both lists. For example, if list list1 and list2 store:
{1, 4, 8, 9, 11, 15, 17, 28, 41, 59}
{4, 7, 11, 17, 19, 20, 23, 28, 37, 59, 81}
Then the call of intersect(list1, list2) returns the list: {4, 11, 17, 28, 59} Note that you can assume that both lists passed store their elements in sorted order. Do not modify the two lists passed in as parameters.
