1-Hour Placement Master Class: DSA, LeetCode & Coding Interviews for BTech & MCA

What will you experience in this 1-hour Master Class? Many students preparing for placements can write basic programs, but struggle when an interviewer gives them an unfamiliar coding problem and asks: “How would you solve this?” The real challenge is often not syntax. It is problem interpretation, logical thinking, algorithm selection and optimization. In this Master Class, we will experience that process with a carefully selected interview-style problem. Our approach will be: 1. Understand the Problem Read the problem like an interviewer expects you to—identify inputs, outputs, constraints and hidden requirements. 2. Construct the Brute-Force Solution Start with a straightforward solution instead of jumping immediately to a memorized trick. 3. Analyze the Bottleneck Ask: Why might this solution fail for larger inputs? We will examine time and space complexity. 4. Discover the Optimized Approach Explore how the right Data Structure or Algorithm can eliminate unnecessary work. 5. Dry Run the Solution Trace the algorithm step-by-step using a practical example so that the logic becomes visible. 6. Implement in Java Convert the reasoning into clean, interview-ready Java code. Where useful, we will also briefly compare how the same idea looks in Python/C++. 7. Connect It to LeetCode & Interviews Understand how the same underlying pattern appears in LeetCode and real coding-round questions. What makes this Master Class different? This is not a one-hour crash course on DSA and not a session where the instructor simply writes a solution on the screen. The objective is to demonstrate how a placement problem is approached from scratch: Problem → Brute Force → Bottleneck → Optimization → Dry Run → Code → Interview Thinking The session is especially relevant for final-year BTech/B.E. and MCA students preparing for campus placements, coding assessments and technical interviews.
