Linked List

A linked list is a linear data structure that consists of nodes. Each Node contains a data field and a pointer to the next Node. In Linked List, unlike arrays, elements are not stored at contiguous memory locations but rather at different memory locations. The various elements in a linked list are linked together using pointers. There are majorly two types of Linked list: Singly Linked List and Doubly Linked List. This category contains all the information you need to know about Linked Lists.
