🔄 Spiral Matrix | LeetCode 54 Java Solution | Explained Step-by-Step

In this video, I explain how to solve the popular LeetCode problem *Spiral Matrix (Problem 54)* using Java. We cover a clear, intuitive approach with boundary pointers (`top`, `bottom`, `left`, `right`) and handle all edge cases.

📌 What you'll learn:
Traversing a 2D matrix in spiral order
Using pointers to track matrix boundaries
Java implementation with `List Integer`
Clean, in-place logic with O(m*n) time


📚 Problem Statement:
Given an m x n matrix, return all elements of the matrix in spiral order.

🧠 Example:
Input: [[1,2,3],[4,5,6],[7,8,9]]
Output: [1,2,3,6,9,8,7,4,5]
