Welcome back to the Python Data Structures & Algorithms Masterclass! 🚀🐍

In this tutorial, we are exploring the Queue data structure. If you’ve ever waited in a line at a grocery store or printer queue, you already know how a queue works! We will break down how this foundational data structure handles data using the FIFO (First In, First Out) principle, look at real-world applications, and write the Python code together. 🧠💻

Whether you're prepping for tech interviews or aiming to write cleaner code, understanding Queues is an absolute must!

💡 Core Queue Operations Covered:
• Enqueue: Adding an element to the back/rear of the queue ➕
• Dequeue: Removing an element from the front of the queue ➖
• Peek / Front: Looking at the first element without removing it 👀
• IsEmpty: Checking if the queue has any elements left 🔍
