![]() ![]() Delete: Removes an element x from a given linked list.An insertion can be done in 3 different ways insert at the beginning of the list, insert at the end of the list and insert in the middle of the list. Insert: Insert a key to the linked list.Search: Find the first element with the key k in the given linked list by a simple linear search and returns a pointer to this element.Circular linked lists - Linked lists where the prev pointer of the head points to the tail and the next pointer of the tail points to the head.Nodes consist of an additional pointer known as prev, pointing to the previous node. Doubly linked list - Traversal of items can be done in both forward and backward directions.Singly linked list - Traversal of items can be done in the forward direction only.Visualization of basic Terminology of Linked Lists (Image by author)įollowing are the various types of linked lists available. The last element of the linked list is known as the tail.įig 2.The attribute named head points to the first element of the linked list.Each node contains a key and a pointer to its successor node, known as next.Elements in a linked list are known as nodes.You can get a clear idea by referring to Figure 2. Let’s consider the following terms regarding linked lists. Linked lists provide a simple and flexible representation of dynamic sets. Hence, you have to access data sequentially and random access is not possible. Used for different sorting algorithms such as insertion sort, quick sort, bubble sort and merge sort.Ī linked list is a sequential structure that consists of a sequence of items in linear order which are linked to each other.Used as the building blocks to build other data structures such as array lists, heaps, hash tables, vectors and matrices.The same goes for the deletion with a new array of reduced size. If you want to insert an element to an array, first you will have to create a new array with increased size (current size + 1), copy the existing elements and add the new element. Inserting elements to an array and deleting elements from an array cannot be done straight away as arrays are fixed in size. Update: Update the value of an existing element at a given index.You can search the element by its value or its index Search: Search for an element in the array.Traverse: Go through the elements and print them.Visualization of basic Terminology of Arrays (Image by author) Array operations
