Data Structures and Algorithms with Python | Free DSA with Python Course - DSA in Python - Implement Stack using Queue | Two Approaches Explained | Part 85 [Hindi]

🚀 Welcome to Part 85 of Code & Debug’s DSA in Python Course! In this video, we implement a Stack (LIFO) using Queue (FIFO), a classic interview problem that tests your understanding of data structure manipulation. We'll explore two different approaches using Python’s queue or deque class. 📚 What you’ll learn in this video: ✅ Difference between Stack and Queue behavior ✅ Approach 1: Costly push() – Efficient pop() ✅ Approach 2: Costly pop() – Efficient push() ✅ Python implementation using deque ✅ Time and space complexity analysis for both approaches 💡 Why is this important? This is a frequently asked interview problem that checks if you truly understand how stacks and queues operate internally. It’s also a stepping stone for solving advanced questions where you're required to simulate one data structure using another. 👉 Link to solve the question: https://leetcode.com/problems/implement-stack-using-queues/description/ 👉 In-Depth Article with Code & Explanations: https://codeanddebug.in/blog/implement-stack-using-queues/ 👉 📄 Access the full YouTube DSA Playlist Sheet (All Questions in Order): 🔗 https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 👉 Enroll in this FREE DSA Python course here: 🔗 https://codeanddebug.in/course/master-dsa-with-leetcode 👉 Enroll for Self-Paced Advanced DSA course here: 🔗 https://codeanddebug.in/course/zero-to-hero-python-dsa 🙏 Thank you for supporting Code & Debug!
