What is Data Structures?
Data Structures are specialized formats for organizing, processing, retrieving, and storing data efficiently. They are the building blocks of computer science and play a vital role in designing efficient algorithms and solving real-world problems.
These notes will help you understand topics like:
Arrays, Strings, and Linked Lists
Stacks and Queues
Trees (Binary Tree, BST, AVL, Heap)
Graphs (BFS, DFS, Shortest Paths, MST)
Hashing and Hash Tables
Searching and Sorting Algorithms
Time and Space Complexity (Big-O Notation)
Why Use Our Data Structures Notes?

Course Units
Unit 1: Introduction to Data Structures
Topics Covered: the basics of data structures including primitive vs non-primitive types, static vs dynamic structures, Big O complexity analysis, arrays with operations, and linked lists such as singly, doubly, and circular lists.
Unit 2: Stacks and Queues
Topics Covered: Explains stacks with array and linked list implementations, operations like push, pop, peek, applications in expression conversion and evaluation, along with queues and their types including simple, circular, priority, and deque.
Unit 3: Trees
Topics Covered: Introduces tree terminology, binary tree representation and types, BST operations like insertion, deletion, searching, tree traversals (inorder, preorder, postorder), and concepts of threaded and AVL trees.
Unit 4: Graphs
Topics Covered: graph basics, types (directed, undirected, weighted), representations using adjacency matrix and adjacency list, graph traversals (BFS, DFS), and applications such as shortest path algorithms and spanning trees.
Unit 5: Sorting and Searching
Topics Covered: Explains sorting algorithms (bubble, selection, insertion), advanced sorting (quick sort, merge sort), searching methods (linear, binary search), and hashing with hash functions and collision resolution strategies like chaining and open addressing.
