which the data items in the memory are not allocated contiguously i.e. the data items are dispersed in the memory. The first data item will have a link to the second data item and second data item will have a link to the third data item and so on. Pros • Uses memory efficiently that the free contiguous memory in not an requirement for allocating data items • The length of the data items is not necessary to be known prior to allocation Cons • Overhead of the link to the next data item Linked

polynomial using linked list? Question 8 Each node of a STACK contains the following information, in addition to required pointer field : i) Roll number of the student ii) Age of the student Give the structure of node for the linked stack in question TOP is a pointer which points to the topmost node of the STACK. Write the following functions. i) PUSH() - To push a node to the stack which is allocated dynamically ii) POP() - To

Data communication is the transfer of data from one device to another via some form of transmission medium. A data communications system must transmit data to the correct destination in an accurate and timely manner. The five components that make up a data communications system are the message, sender, receiver, medium, and protocol. Text, numbers, images, audio, and video are different forms of information. Data flow between two devices can occur in one

Assignment: Binary Search Tree + Heap = Treap October 10, 2012 Binary search tree, as shown in figure 1, is a binary tree data structure which is used to hold key-value pairs and satisfies following properties; • The left subtree of any node contains only those nodes with keys less than the node’s key. • The right subtree of any node contains only those nodes with keys greater than the node’s key. key=10 val="AU" key=8 val="BN" key=15 val="TN" key=12 val="NZ" key=17 val="DL" key=19

Representation of integer has no size restriction • The important factor affecting the running time is normally size of the input. • Normally the built in data type has a fixed size, to enter and to store the larger data. • The Linked List can be used to store the integer without size restriction, which stores each digit in nodes. • The data can also be reused. Addition: A= 456 Represented by 6 → 5 → 4 in linked list B= 094 Represented by 4 → 9 → 0 in linked list The Resultant is C

C++ Data Structures Chapter 1 10) What is the difference between an object and an object class? An object class provides the blue print for an object. It will define everything and all the variables and methods available to an object (at least in non-dynamic languages). An object is an instance of an object class, which provides a living breathing representation of that blue print. Example #1 A Toyota Camry or another particular make might be an instance of the class car. Example

DATA STRUCTURES ANALYSIS OF ALGORITHMS Definition:- The method of solving a problem is known as an algorithm.It is a sequence of instructions that act on some input data to produce some output in a finite number of steps. Properties:- a) Input:An algorithm must receive some input data supplied externally. b)Output:An algorithm must produce atleast one output as the result. c)Finiteness:The algorithm must terminate after a finite number of steps. d)Definiteness:The steps to be performed
