delete − delete elements from the start of the list.insert − insert elements at the start of the list.The most important operations for a circular linked list are: A single linked list and double linked list can be made into a circular linked list. A DLL node has three fundamental members:Ĭircular linked lists function circularly: the first element points to the last element, and the last element points to the first. This ensures that the list can be traversed in both directions. Some common operations for singly linked lists are:ĭoubly linked lists (DLLs) are an extension of basic linked lists, but they contain a pointer to the next node as well as the previous node. ![]() There are a three different types of linked lists that serve different purposes for organizing our code.Ī singly linked list is unidirectional, meaning that it can be traversed in only one direction from head to the last node (tail). Since a linked list is a linear data structure, meaning that the elements are not stored at contiguous locations, it’s necessary to have different types of linked lists to access and modify our elements accordingly. Performing arithmetic operations on long integers.Dynamic memory allocation: use linked lists of free blocks.Implementing HashMaps, File System and Adjacency Lists.Some important applications of Linked Lists include: It is easy to insert and delete from a linked list because unlike arrays, as we only need to change the pointers of the previous element and the next element to insert or delete an element. ![]() Linked lists can dynamically increase in size.
