Fractional Knapsack Explained — Greedy Algorithm Step-by-Step

-
Lecture Link

In this lecture, we introduce the Fractional Knapsack Problem, one of the most important applications of the Greedy Algorithm in optimization. You’ll learn why we use it, where it applies in the real world, and how to design the algorithm step by step. We’ll walk through the intuitive idea behind value-per-weight (density), explore practical examples like resource allocation and profit maximization, and write the pseudoalgorithm you’ll use to solve problems in the next lecture.

System Design Decision Flow 1-  Clarify Requirements    • Functional: What features are needed?      – Example: Store, retrieve, update user profiles; search by email, etc.    • Non-functional: Scale, performance, reliability?     – Example: 100M users, 1000 RPS, 99.99 2-  High-Level Components 2.1- Client         The entry point for user interaction via web or mobile interfaces. Clients send HTTP or API requests to the backend through gateways or load balancers. 2.2- CDN (Content Delivery Network)           A CDN is a globally distributed network of edge servers that caches and serves static content (like images, CSS, JS, fonts, and videos) from locations geographically closer to users. This reduces latency, offloads traffic from your origin server, and improves content delivery speed. Use when: • You serve static assets to a global audience. • You want to reduce load on your a...

Introduction: Are you curious about how websites work? Wondering what makes a website both beautiful and functional? In my latest YouTube video, I break down the difference between frontend and backend development using a relatable home analogy. Whether you’re new to coding or looking to refresh your knowledge, this video is the perfect starting point for your web development journey! What You’ll Learn in the Video: Frontend Development : Learn about the tools like HTML, CSS, and JavaScript that create the visible and interactive parts of a website. Understand how each tool contributes to building a seamless user interface. Backend Development : Discover how frameworks like Django handle data processing, user authentication, and more behind the scenes. See how the backend ensures everything works smoothly. How Frontend and Backend Work Together : Understand why websites need both frontend and backend to function. Explore a practical analogy to make the concept easier to grasp. Than...
