Solving the Median from Data Stream Problem with Heaps

Handling continuous streams of data in real-time is a classic challenge in software engineering, especially when you need to calculate statistical metrics like the median on the fly. This text-only course guides you through the foundational concepts of heaps and walks you step-by-step through implementing the dual-heap pattern to solve the running median problem with optimal time complexity. What you'll learn: • Understand the core mechanics of min-heaps and max-heaps. • Analyze the mathematical logic behind partitioning data streams into two halves. • Implement a robust running median class using clean, type-hinted code. • Balance heaps efficiently during insertion to maintain the correct median structure. • Evaluate the time and space complexity of heap-based streaming algorithms. You will start with fundamental heap concepts and step-by-step logic before diving into structured code exercises and complexity analysis. This course is perfect for beginners to algorithmic patterns and developers preparing for technical interviews, with no advanced prerequisites required.
