In Doubly Linked List, We declare two pointers to store location of next Node and previous Node.
In a doubly linked list, we define a linked list in which each node keeps an explicit reference to the node before it and a reference to the node after it.
Data structure is a way of data organization, management, and storage format that enables efficient access and modification.
In a singly linked list, we have an ordered list of items as individual Nodes that have pointers to other Nodes.
A singly linked list, in its simplest form, is a collection of nodes that collectively form a linear sequence. Each node stores a reference to an object that is an element of the sequence, as well as a reference to the next node of the list.
Big-O notation is a relative representation of the complexity of an algorithm.
A deque, also known as a double-ended queue, is an ordered collection of items similar to the queue. It has two ends, a front, and rear, and the items remain positioned in the collection.
A queue is an ordered collection of items where the addition of new items happens at one end, called the “rear,” and the removal of existing items occurs at the other end, commonly called the “front.”
A stack is an ordered collection of items where the addition of new items and the removal of existing items always takes place at the same end.
