Learn what a linked list is, how it differs from an array, and how to implement and manipulate it in various languages. Explore the types, operations, and performance characteristics of singly and doubly linked lists with code examples. A linked list is a sequence of nodes that contain two fields: data (an integer value here as an example) and a link to the next node. The last node is linked to a terminator used to signify the end of the list . In computer science, a linked list is a linear collection of data elements whose order is not given by their physical placement in memory. Instead, each element points to the next. It is a data structure consisting of a collection of nodes which together represent a sequence. In its ... A linked list is a fundamental data structure in computer science. It mainly allows efficient insertion and deletion operations compared to arrays. Like arrays, it is also used to implement other data structures like stack, queue and deque. Here’s the comparison of Linked List vs Arrays Linked List : Linked List is basically chains of nodes where each node contains information such as data and a pointer to the next node in the chain. It is a popular data structure with a wide range of real-world applications. Unlike Arrays, Linked List elements are not stored at a contiguous location. In the linked list there is a head pointer, which points to the first element of the linked list , and if the list is empty then it simply points to null or nothing. In this article, we will provide a ...
