this presentation is made for the students who find data structure as a typical subject. the slide of this presentation is made in such a manner that student will find the subject topics such as stacks,queues,linklist,array, etc.. very easy to understand. in simple maner this presentation is made by the student of BCA second sem: pooja,shaifali,rani,richa,trishla,pallavi,shivani

8. TREES IN DATA STRUCTURE DREAM VALLEY GROUP OF COLLEGE ADD-NEAR RAILWAY SPRING FACTORY QUARTERS PHONE-2469990

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

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

29. LINKED LIST REPRESENTATION A B C D E H F G THE NODE D,E,F,G AND H CONTAIN A NULL VALUE IN BOTH THEIR LINK FIELD AS THESE ARE THE LEAF

30. ARRAY REPRESENTATION OF BINARY TREE WHEN A BINARY TREE IS REPRESENTATED BY ARRAY THREE SEPRATE ARRAY IS REQUIRED ONE ARRAY ARR STORE DATA FEIDS OF THE TREE THE OTHER TWO ARRAY ARE LC AND RC I.E...... LEFT AND RIGHTCHILD

31. ARRAY REPRESENTATION AR A B C D E F LC 1 2 3 4 5 6 RC 2 6 8 4 9 7 ARRAY

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

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

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

38. 23 41 25 36 12 POP OPERATION ON STACK ( POP ) DELETE 12 FROM THE STACK ( POP ) DELETE 36 FROM THE STACK ( POP ) DELETE 25 FROM THE STACK ( POP ) DELETE 23 FROM THE STACK ( POP ) DELETE 41 FROM THE STACK STACK

39. EXPRESSION :- A + B * C C * B + A scan CONVERSION OF INFIX TO PREFIX NOTATION STACK INFIX PREFIX Character (C) scanned Operator(*) scanned Push (*) into the stack Character (B) scanned Priority of(*)is higher than (+),so(*) operator is poped from the stack Character(A) Scanned Pop(+) from the stack

40. CONVERSION OF INFIX TO POSTFIX NOTATION EXPRESSION :- A + B * C STACK A + B * C INFIX SCAN POSTFIX Character(A) scanned Operator(+) scanned Character (B) scanned Operator (*) scanned Character (c) Scanned Priority of (*) is high, pop(*) from the stack pop (+) from the stack

41. CONVERSION OF PREFIX TO POSTFIX NOTATION EXPRESSION :- + A * B C C B * A + scan PREFIX POSTFIX STACK OPERATOR (+)SCANNED CHARACTER (A) SCANNED OPERATOR (*)SCANNED CHARACTER(B) SCANNED CHARACTER (C)SCANNED Priority of (*) is higher than (+) ,pop (*) from the stack Pop (+) from the stack

42. CONVERSION OF POSTFIX TO INFIX NOTATION EXPRESSION :- A B + C * SCAN A B + C * Operator(*) scanned, push to the stack Character (C) scanned Operator(+) scanned Priority of (*) is higher than (+),so (*) is pop from the stack Push (+) to the stack Scanned character (B) Pop (+) from the stack Character (A) scanned POSTFIX STACK INFIX

48. QUEUE ON GAME STATION

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

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

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

65. THANK YOU

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

70. A linked list consists of several nodes. Each node consists of a data part and a link part. Node Data Link

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
