Efficient Top K Algorithm in C# Using Built-In PriorityQueue

Are you spending your time wisely as a software developer? In this video, I share how I borrowed Rob Moore’s 70/20/10 rule and adapted it to help you grow faster and smarter in your software development career.✅ 70% – Focus on fundamentals and high-ROI learning that compounds over time⚙️ 20% – Invest in skills that boost your productivity in your current team🧪 10% – Experiment with cutting-edge tech to stay ahead of the curveIf you want to stop wasting time and start making intentional progress in your career, this simple framework will help you focus your energy where it matters most.👇 Let me know in the comments: What does your 70/20/10 breakdown look like right now?👉 Like this video if it gave you clarity🔔Subscribe for more practical C# career advice and technical insights📢 Share this with your developer friends who needs this mindset shift!

Want to Level Up Faster? Say YES to These Two QuestionsIf you're serious about accelerating your career, there's a simple test: ✅ Do you have a mentor guiding your journey? ✅ Are you mentoring someone else to solidify your growth?If the answer is no to either, you're likely missing out on one of the most powerful ways to grow faster, smarter, and with more impact.In this short video, I share why mentorship (in both directions) is a game-changer. Not just for technical skills, but for confidence, visibility, and long-term success.🎥 Watch the video, reflect on your mentoring journey, and take action today.👉 If you found this valuable, please share and subscribe to the podcast to for more insights on C# software career and engineering leadership.#mentoring #career #softwaredevelopment #growthmindset

🚀 Boost your .NET skills with this efficient algorithm tip! Want to find the Top K elements from a large dataset without sorting the entire thing?Let me show you how to use the built-in PriorityQueue in .NET to get it done with just O(N log K) complexity 💡It’s a simple but powerful trick: ✅ Use a MinHeap of size K ✅ Keep only the top K elements seen so far ✅ Achieve blazing-fast performance thanks to O(1) min peek📺 I walk through the full solution (with modern C# code)If you found this helpful: 🔁 Share with your fellow devs 👥 Subscribe for more practical .NET tips and software engineering content!

I was a little bored recently and thought to myself, why not implement a Heap data structure in C# from scratch just to keep my mind sharp? 🙂I still remember the first time I came across this data structure at university — I was immediately fascinated. What a clever idea: representing a binary tree using an array and applying a simple invariant to build an in-place, stable sorting algorithm like HeapSort.Now, if you ask most engineers whether they could implement a heap from scratch, they'd probably say no — and that’s perfectly fine. But you don’t want to be just an average engineer, right?If you understand what a Heap is and how to use simple index math to navigate the tree up and down, you can figure out how to implement it — even if you don’t remember the details. Memorizing an algorithm is rarely helpful. Instead, focus on understanding the core concept. Once you do, you’ll find it surprisingly easy to reimplement it whenever needed.IMPORTANT: If you're solving a problem in .NET and need a heap, I strongly recommend using the built-in PriorityQueue class. It’s backed by a quaternary min-heap and optimized for performance. Still, it’s valuable to understand how it works under the hood — and you'll be surprised how few lines of modern C# it takes to implement your own.Happy C# coding!
