This is what the doctor gave us, i asked him he said nothing is missing

Write a method called change Queue to be considered inside the ArrayQueue class and has one parameter item of type E. Your method will change the queue in such a way that if the the first element of the queue and the last element of the queue are equal. the first and last elements in the queue will be replaced with item. otherwise, do not do any change. Similarly, the same process is done for the second element in the queue and the element before the last in the queue and so on. Assume you have a non-empty queue with even number of elements. You are not allowed to call any method from the the ArrayQueue class. Do not use iterators. Method head: public void changeQueue CE item) Example1: Before run: front rear "this" queue: 10 29 2 2510 Item1: 100 After run: front rear "this" queue: 100 29 100 100 5 100
