Master the essential data structures and algorithms that form the foundation of programming problem-solving. In this practical, project-driven course, you’ll work through real-world interview questions and coding challenges to strengthen your logic, sharpen your skills, and build the confidence to tackle technical assessments and professional projects.

Your journey begins with core data structures like stacks, queues, and linked lists, exploring both their implementation and application. You’ll then move into classic interview-style problems such as Two Sum, Min Stack, Max Stack, and linked list reversal, learning the underlying coding patterns and strategies that make these solutions efficient and reusable. As the modules progress, you’ll dive into binary trees and binary search trees, practicing both construction and inversion, before advancing to string manipulation problems such as Detect Capital, reverse strings, and longest palindromic substring. Each step includes hands-on demonstrations and guided explanations to ensure you not only understand the algorithms but also know how to apply them under pressure. By the end of this 13-module course, you will have: - Implemented and practiced essential data structures from scratch. - Solved classic algorithmic problems with confidence and clarity. - Built expertise in binary trees, search trees, and string manipulation. - Developed a strong foundation for technical interviews and real-world coding challenges. This course is ideal for aspiring software developers, computer science students, and professionals preparing for interviews. A basic knowledge of programming in Python, Java, or C++ is recommended, and the intermediate-level design ensures a balance of foundational learning and advanced problem-solving practices that will help anyone looking to perform better in their next programming interview.

In this module, we will explore the practical implementation of essential data structures and hone your problem-solving approach. Learn how to translate conceptual knowledge into code, preparing you for technical interview scenarios.
