Doubly Linked Lists are linked lists in which each node contains two pointers: one pointing to the next node and one to the previous node. Circular Linked Lists connect the last node back to the first node.
struct Node {
int data;
Node* prev;
Node* next;
};
In a circular linked list, the last node points to the first node instead of NULL. It can be singly or doubly linked.
Doubly and circular linked lists provide more flexibility in traversal and structure compared to singly linked lists, making them valuable in many advanced data management scenarios.
