MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Explanation: A linked list is a collection of objects linked together by references from an object to another object. By convention these objects are names as nodes. Linked list consists of nodes where each node contains one or more data fields and a reference(link) to the next node.

Detailed explanation-2: -Linked lists are linear data structures that hold data in individual objects called nodes. These nodes hold both the data and a reference to the next node in the list.

Detailed explanation-3: -Link − Each link of a linked list can store a data called an element. Next − Each link of a linked list contains a link to the next link called Next. LinkedList − A Linked List contains the connection link to the first link called First.

Detailed explanation-4: -The first node in the list is called the head, and the last node in the list is called the tail. To create a singly linked list, we first need to create a node class. Each node will have two data members: an integer value and a reference to the next node in the list.

Detailed explanation-5: -In the linked list, we need to traverse through each element until we reach the nth position. Time taken to access an element represented in arrays is less than the singly, doubly and circular linked lists. Thus, array implementation is used to access the item at the position n.
