Leetcode 509: Fibonacci Number 💡 | Solved Visually by Jagjeet Dangar

🧠 Problem Solved: LeetCode 509 - Fibonacci Number
🎯 Format: Whiteboard Explanation + Logic + Code

In this video, I explain the "Fibonacci Number" problem from LeetCode (Problem #509) using a whiteboard-first approach.

Instead of jumping straight into the code, I:
✔️ Break down what Fibonacci series is
✔️ Do a dry run with initial values
✔️ Then walk through the loop-based solution step by step

This approach ensures you understand how and why the logic works — not just what to type.

💡 Problem Topic: Recursion | Dynamic Programming | Math
