Welcome to another video in the #breakthroughDSA series!
In this video, we’ll learn Queue Data Structure in Python (in Hindi) — starting from absolute basics to advanced concepts, interview questions, and LeetCode problems.

This session is beginner-friendly and explains queues step by step — including theory, real-life analogies, visual intuition, Python implementation (from scratch), and practice questions.

📚 What’s Covered in This Video:

0️⃣ What is a Queue?
1️⃣ Queue vs Stack — FIFO vs LIFO
2️⃣ Real-life examples of Queue
3️⃣ Operations on Queue (enqueue, dequeue, peek, isEmpty, size)
4️⃣ Implementing Queue using:
Python List
Fixed-size Array (Linear Queue)
Circular Queue (using modulo arithmetic)
Linked List
collections.deque (Pythonic implementation)
5️⃣ Queue using Two Stacks — Interview Question
6️⃣ Common MCQs on Queue
7️⃣ Important LeetCode Questions on Queue
