🚀 Welcome to Part 87 of Code & Debug’s DSA in Python Course! In this lecture, we implement both Stack (LIFO) and Queue (FIFO) using a Doubly Linked List from scratch. This approach gives you full control over memory and pointer manipulation — crucial for mastering low-level data structures. 📚 What you’ll learn in this video: ✅ Basics of Doubly Linked List structure (prev & next pointers) ✅ Implementing a Stack using DLL (push, pop, peek) ✅ Implementing a Queue using DLL (enqueue, dequeue, front, rear) ✅ Understanding time & space complexities of all operations ✅ Real-world scenarios where DLL-based stack/queue is useful 💡 Why is this important? Implementing data structures manually improves your core DSA foundation and helps in solving custom linked-list based interview questions. This concept is useful in designing LRU Caches, Undo-Redo Systems, and Scheduling Queues. 👉 Link to solve the question: https://www.geeksforgeeks.org/problems/implement-stack-using-linked-list/1 https://www.geeksforgeeks.org/problems/implement-queue-using-linked-list/1 👉 In-Depth Article with Code & Explanations: https://codeanddebug.in/blog/implement-stack-using-linked-list/ https://codeanddebug.in/blog/implement-queue-using-linked-list/ 👉 📄 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!
