Data Structures and Algorithms with Python | Free DSA with Python Course - DSA in Python - Implement Queue using Stack | Using Two Stacks Explained | Part 86 [Hindi]

🚀 Welcome to Part 86 of Code & Debug’s DSA Python Course! In this video, we implement a Queue (FIFO) using two Stacks (LIFO) — a popular interview question that tests your understanding of data structure reversal logic and internal simulation techniques. 📚 What you’ll learn in this video: ✅ Understanding the core difference between Stack and Queue ✅ Using two stacks to mimic queue behavior ✅ Implementation of enqueue() and dequeue() ✅ Time & space complexity of both operations ✅ Real-world use cases and dry run explanation 💡 Why is this important? This question is commonly asked in coding interviews to evaluate how well you can apply stack behavior to simulate queue operations. It's also a great way to develop a deeper intuition around stack reversal and amortized analysis. 👉 Link to solve the question: https://leetcode.com/problems/implement-queue-using-stacks/description/ 👉 In-Depth Article with Code & Explanations: https://codeanddebug.in/blog/implement-queue-using-stacks/ 👉 📄 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!
