Level order traversal | # 80 GFG 160-Day Challenge| GFG POTD

In this video, we tackle the Level Order Traversal Problem a fundamental tree traversal technique frequently asked in coding interviews and competitive programming contests. We will explore how to traverse a binary tree level by level using a systematic approach.

🔍 What You'll Learn in This Video:

- Understanding the concept of Level Order Traversal in binary trees.
- Implementing the Breadth-First Search (BFS) approach to traverse the tree level by level.
- How to use a queue data structure to efficiently perform the traversal.
- Writing clean and optimized code in C++/Python.

💡 Problem Statement Highlights:

Given a binary tree, the goal is to print the nodes of the tree in level order, i.e., from left to right, level by level.

🛠 Approach Used:

- Breadth-First Search (BFS) – Using a queue to process nodes level by level.
- Queue Data Structure – Storing nodes at each level and processing them in FIFO order.
- Optimizations – Ensuring the solution is efficient in terms of time and space complexity.
