Finish a method reverseHalf that reverses the order of half of the elements of a Queue of integers. Your method should reverse the order of all the elements in odd-numbered positions (position 1, 3, 5, etc.) assuming that the first value in the queue has position 0. For example, if the queue originally stores this sequence of numbers when the method is called: index: 0 1 2 3 4 5 6 7 front (1, 8, 7, 2, 9, 18, 12, 0] back - it should store the following values after the method finishes executing: index: 0 1 2 3 4 5 6 7 front (1, 0, 7, 18, 9, 2, 12, 8] back Notice that numbers in even positions (positions 0, 2, 4, 6) have not moved. That sub-sequence of numbers is still: ( 1 , 7, 9, 12). But notice that the numbers in odd positions (positions 1, 3, 5, 7) are now in reverse order relative to the original. In other words, the original sub-sequence: ( 8 , 2, (18), 0 ) - has become: (0, 18 , 2, 6). Below is the code. What small piece of code goes in the highlighted section to make this program work. It needs to be exact to compile(all lower case etc..) Feel free to test in Eclipse if needed. public void reverseHalf (Queue<Integer> q) { Stack<Integer s = new Stack<Integer>(); int oldSize = q.size(); for(int i = 0; i < oldSize; i++) { if(i % 2 == 0) { q.add(q.remove()); } else { s.push(q.remove()); } } for(int i = 0; i < oldSize; i++) { if(i % 2 == 0) { q.add(q.remove(); } else { q.add(*******); } } }
