Stacks follows Last in first out(LIFO) principle. What is Stack?Ī stack is a non primitive data type linear data structure ordered list, in which the addition of new data and deletion of data takes place from one end, known as top.Įlements can’t be deleted or inserted from the middle of the stack. A circular linked list can be a singly circular linked list or doubly circular linked list.We can traverse the complete linked list by starting from any point in the list. What is Circular Linked List?Ĭircular linked list is a linked list, in which all nodes are connected to form a circle i.e last node points to the first node of the list. Operations like adding, deleting a node require more changing more links than singly linked list. The last node always points to null.We can traverse in both direction. What is Doubly Linked List?Ī doubly Linked list is a linear data structure, in which link store reference to the next node as well as to the previous node. It is also known as one-way list.We cannot traverse in backwards direction. It’s size can be changed during the run time i.e dynamically. What is Singly Linked List?Ī singly Linked list is a linear data structure, in which link only store reference to the next node. Other one is link, which contains the pointer to next node or previous node or both, that holds the address of the node. First is data part, which is used to information of the element in the list. What is Linked List?Ī Linked list is a linear data structure, which contains two parts. It represents a logical relationship between data and its function.ĭata Structures is about creating data elements in terms of some relationship, for organizing and storing them in a better way. Data Structure is the method of arranging data in such a way that it can be used to perform common and most frequent operations effectively and efficiently.
