Fibonacci Number | Dynamic Programming | Intuition |Memoization, Tabulation | Must DO | MAANG Prep In this video, we solve the Fibonacci Number problem using Dynamic Programming, one of the most important and must-watch problems to understand DP fundamentals. This session explains why Fibonacci is a Dynamic Programming problem, how overlapping subproblems occur, and how we optimize a recursive solution using memoization and tabulation. 🔹 Fibonacci using recursion (why it fails) 🔹 Overlapping subproblems explained clearly 🔹 Fibonacci using Memoization (Top-Down DP) 🔹 Fibonacci using Tabulation (Bottom-Up DP) 🔹 Time and space complexity comparison 🔹 How Fibonacci builds DP intuition for interviews This problem forms the foundation of Dynamic Programming and helps you understand how to approach interview-level DP questions logically and efficiently. If you are preparing for placements, coding interviews, or MANG interviews, mastering Fibonacci with DP is the first and most important step.
