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.
