    • Array is vital part of programming. It allows user to stored multiple value in single variable. Array stored in contiguous form in memory.
    INTRODUCTION TO ARRAY
  • 5. A B C F E D Array representation on memory OR INSERTION OF ELEMENT IN THE ARRAY
  • 6. operation performred on array
    • Traversal:- processing each element in the array .
    • Search:- finding a location of an element in the given value.
    • Insertion:- adding new element in array.
    • deletion:- removing an element in array.

  • 9. TREES IN DATA STRUCTURE PRESENTED BY- GUIDED BY- HARISH SIR PUJA AND SHAIFALI
  • 10. TOPIC COVERED WHAT IS TREE ROLE OF TREE IN DATA STRUCTURE BUILDING A SIMPLE TREE TYPES OF TREES BUILDING A BINARY TREE INORDER PRE ORDER POST ORDER ARRAY LINKED LIST
  • 11. WHAT IS TREE TREES BRANCHES LEAVES ETC
  • 12. NATURE IS A MAN'S BEST TEACHER IF YOU UNDRESTAND THE CONCEPT OF TREE IT MEANS SIMPLE TREE --> CHILD NODE <- ROOT NODE/PARENT NODE
  • 13. BUT IN DATASTRUCTURE TREE IS CREATED LIKE THIS BUT IN REVERSE FORM --> TREES IN REVERSE FORM -> child node <- root node
  • 14. IN A TREE STRUCTURE,HOWEVER EACH NODE MAY POINT TO SEVERAL NODE.
  • 15. Binary tree->binary tree is defined as finite set of node in which number of the children of a node should not exceed more than two .it means the degree of binary tree not then greater then two .
  • 16. BINARY TREE A B C D E F G THIS IS A BINARY TREE ROOT NODE CHILD NODE BRANCHES
  • 17. TYPES OF BINARY TREE STRICTLY BINARY TREE COMPLETE BINARY TREE EXTENDED BINARY TREE
  • 18. In every non terminal node in a binary tree consists of non empty left subtree and right subtree ,then such a tree is called strictly binary tree . STRICTLY BINARY TREE
  • 19. STRICTLY BINARY TREE A B D E C F G NON TERMINAL NON TERMINAL
  • 20. Complete binary tree The level of all nodes of complete binary tree is equal .
  • 21. A B C D E F G complete binary tree 0 1 2 THESE ARE LEVEL OF COMPLETE BINARY TREE AND THE LEVEL OF THIS COMPLTE BINARY TREE IS 2
  • 22. building a binary tree element are to be added 20 7 26 8 18 6 28 20 20 is a root node of this tree > 7 7 is compared with 20 7 > 26 26 is compared with 20 26 7 AND 26 IS CHILD NODE OF THE ROOT TREE > 8 8 IS COMPARED TO 26 THEN COMPARED TO 7 > 8 8 > 6 6 IS COMPARED WITH 20 AND 7 > 6 6 < 18 < 18 18 18 IS COMPARED WITH 20 AND 26 > 28 > 28 28 IS COMPARED WITH 20 AND 26 28 THIS IS THE BUILDING OF BINARY TREE THEN.. TRAVERSAL OF A BINARY TREE
  • 23. printing the data in in-order trversal
    • To traverse a non empty binary tree in in-order following three operations are performed
    • Traverse the left sub –tree in in-order
    • Visit the root node
    • Traverse the right sub-tree in in-order
    A B C D E F G TRVERSE STARTS FROM THE ROOT NODE Since D is the leaf node ,it gets printed ,which is the left child of D. D Now B gets printed as it is the parent of the node D B Since E is the leaf node ,it gets printed ,which is right child of B E Now A gets printed as it is the parent of the node B A Since F is the leaf node ,it gets printed ,which is the left child of c F Now C gets printed as it is the parent of the node F C Since G is leaf node ,it gets printed ,which the right child of C G In order traversal
  • 24. Post -order traversal Printing the data in post-order traversal
    • To traverse a non empty binary tree in in-order following three operations are performed
    • Traverse the left sub –tree in in-order
    • Visit the root node
    • Traverse the right sub-tree in in-order
    A B C D E F G Now A gets printed as it is the parent of the node B Now C gets printed as it is the parent of the node F Since D is the leaf node ,it gets printed ,which is the left child of D. TRVERSE STARTS FROM THE ROOT NODE Now B gets printed as it is the parent of the node D D E B Now F gets printed as it is the left child of C F G C A Since E is the leaf node ,it gets printed ,which is right child of B Now G gets printed ,as it is the right child of C
  • 25.
    • a non empty binary tree in pre-order following three operations are performed To traverse
    • Visit the root node
    • Traverse the left sub –tree in pre-order
    • Traverse the right sub-tree in pre-order
    Pre-order traversal A B C D E F G Printing the data in pre-order traversal Traversal starts from the root node The data at the root node i.e. A gets printed A Since D is the leaf node ,it gets printed ,which is the left child of B. D Now B gets printed as it is the parent of the node D B Since E is the leaf node ,it gets printed , which is right child of B E Now C gets printed as it is the parent of the node F C Since F is the leaf node ,it gets printed , which is the left child of c F Since G is leaf node ,it gets printed , which the right child of C G
  • 26. Representation of a binary trees in memory ->there are two ways by which we can represent a binary tree LINKED LIST ARRAY ARRAY LINKED LIST
  • 27. BINARY TREE CAN BE REPRESENTED BY LINKS WHERE EACH NODE CONTAINS THE ADDRESS OF THE LEFT CHILD AND THE RIGHT CHILD
  • 28. LINKED LIST REPRESENTATION LEFT DATA RIGHT NODE

  • 32. PPT PRESENTATION ONSTACK DATA STRUCTURE BCA 2nd semester Dept. of computer science Presented by:- Guided by:- RICHA MITTAL HARISH SIR RANI KUSHWAH
  • 33. CONCEPT OF STACK
  • 34. Topic Covered
    • Introduction .
    • Working of stack
    • Push operation performed on stack
    • Pop operation performed on stack
    • Infix to prefix
    • Infix to postfix
    • Prefix to postfix
    • Postfix to infix
  • 35. A Stack is a linear collection of data in which new item may be inserted and deleted at one end. It sometimes called LIFO and push down list . A stack is usually represented by computer by block of memory cells. Thus, stack data structure implemented (LIFO) property. The situation of LIFO may be compared as the plates of cafeteria where every new plate will added at the top. INTRODUCTION TO STACK
  • 36.
    • Working of stack
    • Stacks associated with two basic operation i.e PUSH and POP.
    • Push function means addition of element to the stack.
    • Pop function means remove an element from the top op the stack.
  • 37. 23 41 25 36 12 Push Operation on stack ( PUSH ) INSERT 41 TO STACK ( PUSH ) INSERT 23 TO STACK ( PUSH ) INSERT 25 TO STACK ( PUSH ) INSERT 36 TO STACK ( PUSH ) INSERT 12 TO STACK STACK

  • 53. GRAPHS IN DATA STRUCTURE GUIDED BY-HARISH SIR PRESENTED BY-PUJA SONI
  • 54. GRAPHS IE….. SPREAD YOUR TENTACLES
  • 55. I N COMPUTER SCIENCE,GRAPH IS USE TO CREATE ROAD STRUCTURE MAPS AEROPLANE MAPS ETC...
  • 56. N ETWORKING! BE IT ANY WALK OF LIFE THAT’S THE KEY WORD TODAY BETTER YOUR NETWORK,FARTHER YOU WOULD REACH AND FUTHER YOU REPLACE YOUR TENTACLES BETTER WOULD YOU NETWORK, AND THE CRUX OF BUILDING AND MANAGING A NETWORK IS HIDDEN IN A SUBJECT AS INNOCUOUS AS DATA STRUCTURE IN A TOPIC CALLED GRAPHS
  • 57. TERMINOLOGY THE NATURAL WAY TO UNDERSTAND A GRAPH IS TO REPRESENT VERTICES AS POINT OR CIRCLES AND EDGES AS LINE SEGEMENT OR ARCS CONNECTING THE VERTICES
  • 58. GRAPHS
    • THIS CONCEPT INTRODUCE IMPORTANT MATHAMATICAL STRUCTURE CALLED GRAPHS
    • APPLICATION IN SUBJECT AS DIVERSE AS SOCIOLOGY,CHEMISTRY GEOGRAPHY AND ELECTRICALLY ENGINEERING
  • 59. APPLICATION OF GRAPHS NOW A DAYS MANY APPLICATION RELATED WITH COMPUTATION RELATED WITH COMPUTATION CAN BE MANAGED EFFICIENTLY WITH GRAPH DATA STRUCTURE computer network Vertices in the graph might represent computer instollation, edges represent connection between computers.where we want to allow message from any computer to get any other possibility with routing through intermidiate computer with minimum cost of connection air lines routes vertices in a graph are cities and edges are root between cities we want to service a connected set of cities with minimum cost
  • 60. TYPES OF GRAPHS
    • DIRECTED GRAPH
    • UNDIRECTED GRAPH
    IN THIS TYPE OF GRAPH PATH IS SPECIFIED THAT TYPE OF GRAPH IS CALLED DIRECTED GRAPH IN THIS TYPE OF GRAPH PATH IS NOT SPECIFIED IN THIS TYPE OF GRAPH THIS TYPE OF GRAPH IS CALLED UNDIRECTED GRAPH
  • 61. selected south pacific air route this is also a graph THERE ARE MANY KINDS OF GRAPH
  • 62. THE VARIOUS KIND OF UNDIRECTED GRAPH CONNECTED PATH THERE ARE SEVERAL UNDIRECTED GRAPH.TWO VERTICES IN AN UNDIRECTED GRAPH IS CALLED ADJACENT IF THERE IS AN EDGE OFROM FRIST TO THE SECOND ADJACENT
  • 63. DIRECTED GRAPH THIS IS DIRECTED GRAPH BECAUSE PATH IS SPECIFIED IN THIS GRAPH
  • 64. CONNECTED DISCONNECTED PATH CYCLE TREE THESE ARE THE VARIOUS KIND OF UNDIRECTED GRAPH

  • 67. Link list as data structure
  • 68. LINK LIST Definition: In computer science linked list is a data structure that consist of a sequence of data record such that in each record there is a field that contains a reference of next record in a sequence
  • 69.
    • Link list are special list of some data element link to one another. each element in link list called a node. Each node in a link list must contain at least two fields. An information field and next address field. The information field contain the actual element on the list which may be a integer, character, string or a large records.
  • 70. A linked list consists of several nodes. Each node consists of a data part and a link part. Node Data Link
  • 71. Use of Linked List
    • Linked list as a data structure was used to solve many computer problem with a language called IPL. The major use of linked list to develop
    • 1- Artificial intelligence
    • 2- Chess Program
    • 3- General Problem Solver
  • 72. Advantage of link list
    • Link list are dynamic data structure.
    • Efficient memory utilization that is memory is not pre allocated memory allocated . When ever it is required and is de allocated when it is no longer required.
    • Insertion and deletion are easier and efficient
    • Many complex application can easily handle with link list.
  • 73. Disadvantage of link list
    • 1.many complex required because each node contain more fields.
    • 2.access to a particular node is little bit cumber some and time consuming.
  • 74. Building a linked list Node Data Link 70 NULL 100 80 NULL 200 90 NULL 300 300 200
  • 75. 10 20 30 100 200 300 NULL This is linked list of 3 nodes Allocate memory for a new node 700 Set 99 value in data part of new node 99 Set link part of a new node ,with the address of first node Adding a new node at the beginning
  • 76. DELETION OF A NODE IN A LINK LIST 45 56 80 75 200 300 400 500 Initially link contain four nodes. Set links to the node. Delete third node from the list null Set value to the nodes FREE THE MEMORY OCCUPIED BY THIRD NODE
  • 77. Types of link list
    • Basically four types of link list :
    • 1 singly link list.
    • 2 doubly link list.
    • 3 circular link list.
    • 4 doubly and circular link list.
  • 78. Singly link list
    • A singly link list is one in which all nodes are linked together in same sequential manner . It is also called linear link list . It has the beginning and the end. The main with this list is that we cant access the previous node from the current node. This problem can be over come with link list . In this list each node divided in to two parts that is INFO AND NEXT.
  • 79. SINGLY LINK LIST START A . . X INFO PART ADDRESS PART B C
  • 80. Doubly link list
    • A doubly link list is one in which all nodes are linked together by multiple link which is used in accessing next node and previous node from the curve node in the list .Each node in a doubly link list field to the left node and the right node .This help to traversed the list in the forward direction and the backward direction .So doubly link list provide bi directional traversing .each node in a doubly list is divided in three parts.
    • INFO: To contain the information .
    • NEXT: To contain the pointer to the next node.
    • BACK :To contain the pointer to the previous node.
  • 81. DOUBLY LINK LIST BACK INFO NEXT
  • 82. START . A . . B . . C X
  • 83. Circular link list
    • A circular link list is one which having no of beginning and no of end . A singly link list in which the link field of the last node contain the address of the first node of the list .That is the last field of the last node does not contain the null pointer rather it point back to the beginning of the link list.
  • 84. CIRCULAR LINK LIST START A B C . . .
  • 85. DOUBLY CIRCULAR LINK LIST
    • A doubly circular link list is one which has both the successor pointer and procedure pointer in circular manner .A dell is a variation of doubly link list
  • 86. DOUBLY CIRCULAR LINK LIST START . A . . . . C . B
