Mastering Data Structures & Algorithms for Placement

🧠 Course Objective

This course is designed to help students master the fundamentals and advanced concepts of Data Structures and Algorithms (DSA) — essential for technical interviews, competitive coding, and product-based company placements.

Students will learn to analyze time and space complexity, solve real-world problems, and ace coding tests and interviews at companies like TCS, Infosys, Wipro, Amazon, Microsoft, Google, and more.
