A doubly linked list (DLL) is a type of linked list in which each node has a pointer to both the previous and next node in the linked list.
A double-linked list is an upgrade of a singly linked list, with each node consisting of three components:
A doubly linked list consists of nodes with a value and two pointers: prev and next, allowing bidirectional traversal. The head node's prev pointer points to NULL, while the tail node's next pointer points to NULL, indicating the start and end of the list.
A Doubly Linked List is represented by linear arrays in memory, with each memory address storing three components:
