Suppose you have a balanced tree implementation in which Insert(x, T), Delete(x, T), Successor(x, T), and Predecessor(x, T) all take O(log n)-time. Describe how you would change the implementation and/or data structure so that Successor and Predecessor run in 0(l)-time and Insert and Delete remain 0(log n)-time. Be sure to clearly explain how each of the operations change.
