PPT-Doubly Linked Lists

Linking in double direction A doubly linked list is a linked list in which every node has a next pointer and a back pointer A doubly linked list can be traversed in either direction That is we can traverse the list starting at the first node or if a pointer to the last node is given we can traverse the list starting at the last node. Singly linked lists are flexible structures where memory can be allocated in small blocks as needed Also when deleting or inserting nodes from a singly linked list the overhead is re latively low compared to array insertions where array elements ha Unlike singly linked lists where traversal is only one way doubl y linked lists allow traversals in both ways A generic doubly linked list node can be desi gned as typedef struct node void data struct node next struct node prev node node head nod doubly-diminisheddoubly-diminished doubly-diminished diminished diminisheddiminished diminisheddiminishedthirteenth chord diminished diminisheddiminished diminishedminorthirteenth chord diminished dim CS303E: Elements of Computers and Programming.
