Memory-Efficient Doubly-Linked-Lists Recall that a memory efficient doubly-linked list implements the List interface by storing a sequence of blocks (arrays) each containing b ± l elements. What is the running-time of get(i) and set(i) in a memory-efficient doubly-linked list? What is the amortized (or average) running time of the add(i) operation in a memory-efficient doubly-linked list? In a memory-efficient doubly-linked list containing n elements, what is the maximum amount of space that is not devoted to storing data
