Redo the previous problem, but providing an implementation within the class LinkedPositionalList that does not create or destroy any nodes.
Exercise C- 7.39
Suppose we want to extend the PositionalList abstract data type with a method, moveToFront(p), that moves the element at position p to the front of a list (if not already there), while keeping the relative order of the remaining elements unchanged. Show how to implement this method using only existing methods of the PositionalList interface (not details of our LinkedPositionalListimplementation).
