Master Heaps and Priority Queues with these focused, beginner-friendly notes designed to simplify one of the most powerful data structures in DSA. These notes help you understand the core logic behind heaps, operations, and how they're applied in real coding problems.

What’s Covered:

• What is a Heap? (Min-Heap & Max-Heap)
• Heap Insertion & Deletion Operations
• Heapify Process (Building a Heap)
• Heap Sort Algorithm
• Priority Queue in C++ (STL Implementation)
• Important Interview & OA Questions (LeetCode, GFG, etc.)

Students often struggle with the logic behind heapify and STL usage — these notes break it down with clarity. They’re great for quick revision and understanding heaps from both a theoretical and implementation perspective.
