PPT-Linked lists A linked list is a collection of components called

nodes Every node except the last one contains the address of the next node The address of first node is stored in separate location called as head or first Every node in linked list has 2 components. Linked List Linked List Linked List
Linked List List
 Example: An array
The array index is used for accessing and manipulation of array elements  Problems with arrays  Problems with arrays class List { List() { head = new Node; head-next = head-prev = head; } // destructor virtual ~List() { Node *p = head-next; while (p != head) { Node *next = p-next; delete p; 1.
