๐ Welcome to Part 164 of Code & Debugโs DSA in Python Course! In this video, we solve the classic problem: Reverse a Doubly Linked List from GeeksforGeeks. Weโll walk through the logic step-by-step and implement an efficient Python solution that swaps the prev and next pointers for each node to reverse the DLL in-place. This approach is a must-know for interviews and strengthens your understanding of pointer manipulation in linked lists. ๐จโ๐ซ Whatโs covered in this video: 1. Understanding the problem statement from GFG 2. Step-by-step logic to reverse a doubly linked list 3. Swapping prev and next pointers in each node 4. Handling edge cases (empty list, single node) 5. Complete Python code walkthrough 6. Time and Space Complexity analysis By the end of this session, youโll be confident in reversing any doubly linked list and explaining your approach in interviews! ๐ GFG Problem - Reverse a Doubly Linked List: https://www.geeksforgeeks.org/problems/reverse-a-doubly-linked-list/1 ๐ Refer to the article for better understanding: ๐ https://codeanddebug.in/blog/reverse-a-doubly-linked-list/ ๐ Full Playlist Sheet (All Questions in Order): https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing ๐ Enroll in the FREE Python DSA Course: https://codeanddebug.in/course/master-dsa-with-leetcode ๐ Advance Python DSA for FAANG (Zero to Hero Course): https://codeanddebug.in/course/zero-to-hero-python-dsa Stay focused and keep coding with Code & Debug.
