Linked List
A linked list is a linear data structure where elements, called nodes, are connected using pointers. Each node contains data and a reference to the next node, allowing dynamic memory allocation and efficient insertion or deletion. Common types include singly, doubly and circular linked lists, widely used in data manipulation and memory management.
