Linked lists Motivation: we can make arrays, but their functionality is slightly limited and can be difficult to work with Biggest issue: size management.

Algorithm for deleting a node from a singly linked list Algorithm delete (front,nodeToDelete) In: front node of linked list and node to delete Out: true if the node was deleted, false otherwise current = front prev = null while (current != null) and (current != nodeToDelete) do { prev = current current = current.next } if current == null then return false else { if prev != null then prev.next = current.next else front = front.next return true

Doubly Linked List Node object element prev next front tail

Java Class for a Node of a Doubly Linked List public class LinearNodeDLL<T> { private LinearNodeDLL<T> next; private LinearNodeDLL<T> prev; private T element; public LinearNode( ) { next = null; prev = null; element = null; } public LinearNode (T dataItem) { element = dataItem;
