an element The number of positions on a list equals the length of the list. It is possible for the same element to appear at two or more positions. Thus it is important not to confuse a position with the element at that position. For instance, list (3) in Example 6.1 has twelve positions, seven of which hold 31 — namely, positions 1, 3, 5, 7 ...

• Remove and save the least element – (at the root) • This leaves a hole at the root – Move last element of the heap to the root. • Bubble element down –always with smaller child, until heap invariant is true again. • The heap invariant is maintained! 44 poll() Time is O(log n), since the tree is balanced

The linear structures In general, a linear list is a data object whose values are of the form (e1,e2,···,en), where eiterms are the elements of the list, and n, a finite number, is its length. When n =0, the list is empty. Otherwise, e1 is the first element, and en is the last one. For

• A linked list is a data structure which can change during execution. – Successive elements are connected by pointers. – Last element points to NULL. – It can grow or shrink in size during execution of a program. – It can be made just as long as required. – It does not waste memory space.

E element; DNode next; DNode prev;:}} The key advantage of doubly linked lists over a singly linked list is that the former allows us to quickly access elements near the back of the list. For example, to remove the last element of a doubly linked list, one simply does the following: tail = tail.prev tail.next = null size = size-1 Dummy nodes
