Understand what data structures are and why they matter. You'll review pointers and dynamic memory allocation in C++, then dive into arrays — the simplest structure — and learn to analyze algorithm efficiency using Big-O notation.

Master the most flexible data structure: linked lists. You'll implement singly, doubly, and circular linked lists, and apply them to build real-world features like a music playlist and an undo-redo system.
Learn LIFO and FIFO data structures. You'll implement stacks and queues using arrays and linked lists, and apply them to expression evaluation, browser back-button, and task scheduling.
Master linear and binary search, and six sorting algorithms. You'll analyze their time complexities and learn when to use each. Example: sorting employee salaries at TCS.
Explore graph terminology, representations (adjacency matrix/list), and traversal algorithms (DFS, BFS). Apply them to real-world problems like shortest path in Google Maps and social network connections.
Learn dictionary ADT and hash tables. Implement hash functions, handle collisions via chaining and open addressing, and understand rehashing. Example: building a phone book for a telecom company.
Master binary trees, BSTs, AVL trees, B-trees, and B+ trees. Implement operations and understand balancing. Example: building an autocomplete feature like Google Search.
