Data Structures and Algorithms with Python | Free DSA with Python Course - DSA in Python Course - Kth Largest Element in a Stream | Min Heap Design | Medium | Part 189

📘 Welcome to Part 189 of Code & Debug's DSA in Python Course! Building on your mastery of QuickSelect algorithm from the previous session, we now tackle a related but distinct problem: Kth Largest Element in a Stream from LeetCode. This time, we'll design a class that efficiently maintains the kth largest element in a continuously growing stream of numbers using a Min Heap of size k, making it perfect for real-time data processing scenarios. This problem demonstrates the power of heap-based design patterns and is frequently asked in system design and streaming data interviews at top tech companies! 👨‍🏫 What's covered in this video: ✅ Understanding the problem: Stream vs. Static Array ✅ Why Min Heap is perfect for this streaming scenario ✅ Complete KthLargest class implementation in Python ✅ Constructor initialization with existing numbers ✅ Add method for inserting new elements efficiently ✅ Maintaining heap size to exactly k elements ✅ Time Complexity: O(log k) per insertion analysis ✅ Space Complexity: O(k) for optimal memory usage ✅ Interview tips and edge cases handling By the end of this session, you'll master heap-based class design and understand how to handle streaming data efficiently using priority queues! 🔗 LeetCode Problem - Kth Largest Element in a Stream: https://leetcode.com/problems/kth-largest-element-in-a-stream/description/ 📄 Full Playlist Sheet (All Questions in Order): https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 🎓 Enroll in the FREE Python DSA Course: https://codeanddebug.in/course/master-dsa-with-leetcode 🚀 Advance Python DSA for FAANG (Zero to Hero Course): https://codeanddebug.in/course/zero-to-hero-python-dsa Stay focused and keep coding with Code & Debug.
