6)The Complete Greedy Algorithms Roadmap: 8 Essential Patterns from Beginner to Expert (2026 Guide)
Greedy Algorithms are the “Smart Shortcuts” of Computer Science. While Dynamic Programming meticulously calculates every possibility ($O(N^2)$), a Greedy Algorithm makes the best local choice at every step ($O(N \log N)$ or $O(N)$) and hopes it leads to the global optimum. For top-tier interviews, you must know when to be greedy and when to stop. … Read more
