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.
