Syllabus: Data Structures Notes
UNIT – 1
(a) Introduction to Data Structures –
i) Definition, types (primitive & non-primitive)
ii) Static vs dynamic structures
iii) Complexity analysis – Big O notation
iv) Arrays – representation, operations (insertion, deletion, traversal)
(b) Linked Lists –
Singly linked list – creation, insertion, deletion
Doubly linked list – operations
Circular linked list – features and operations
UNIT – 2
Stacks and Queues:
Stack – concept, array & linked list implementation
Operations – push, pop, peek
Applications – expression conversion (infix to postfix), postfix evaluation
Queue – array & linked list implementation
Types – simple, circular, priority, deque
UNIT – 3
Trees:
Basic terminology – nodes, edges, degree, level, height
Binary trees – representation, types
Binary search tree (BST) – insertion, deletion, searching
Tree traversals – inorder, preorder, postorder (recursive & non-recursive)
Threaded and AVL trees – basic concept
UNIT – 4
Graphs:
Definition and types – directed, undirected, weighted
Representation – adjacency matrix and adjacency list
Graph traversals – BFS and DFS
Applications – shortest path (intro to Dijkstra), spanning trees
UNIT – 5
Sorting and Searching:
Sorting algorithms – bubble sort, selection sort, insertion sort
Advanced sorts – quick sort, merge sort
Searching techniques – linear search, binary search
Hashing – concept, hash functions, collision resolution (chaining, open addressing)
