🧠 Why Watch This Video?
DSA is one of the most scoring yet tricky subjects in Computer Science. Many students struggle with proper time management during paper attempts or misunderstand the logic behind the questions.
This video not only solves the past paper but explains the reasoning behind every step — no shortcuts, just clear and concise learning.
🛠️ Topics Covered from Past Paper:
Time Complexity of loops and algorithms
Array operations & tricky index calculations
Stack and Queue implementations (including CircularQueue)
Linked List traversal and insertion/deletion logic
Binary Tree traversals: Inorder, Preorder, Postorder
Heap Tree properties & implementation
Graph concepts like BFS, DFS, and Minimum Spanning Tree (Prim’s and Kruskal’s Algorithms)
Hash Tables & collision resolution methods
Expression Evaluation using Stack
Code-based MCQs and theoretical short questions
📝 Includes:
🔹 Clear dry-run of codes
🔹 Explanation of logic behind each correct answer
🔹 Shortcuts and tips to save time in the exam
🔹 Highlighting commonly repeated question types
🔹 Breakdown of marks distribution per question type
🎓 Perfect For:
