DSA in Python - Delete All Occurrences of a Key in Doubly Linked List | GFG Practice | Part 165

📘 Welcome to Part 165 of Code & Debug’s DSA in Python Course! In this video, we tackle the important problem: Delete All Occurrences of a Given Key in a Doubly Linked List from GeeksforGeeks. We’ll break down the logic to efficiently remove every node containing the target value, handle edge cases, and update the prev and next pointers correctly. This problem is essential for mastering pointer manipulation and understanding how to maintain the integrity of a doubly linked list during deletions. 👨‍🏫 What’s covered in this video: 1. Problem statement explanation from GFG 2. Step-by-step approach to delete all nodes with a specific value 3. Handling deletions at head, middle, and tail 4. Properly updating prev and next pointers 5. Complete Python code walkthrough 6. Edge cases and tips for interviews 7. Time and Space Complexity discussion By the end of this session, you’ll be able to confidently solve deletion problems in doubly linked lists and explain your solution in interviews! 🔗 GFG Problem - Delete all occurrences of a given key in a doubly linked list: https://www.geeksforgeeks.org/problem... 👉 Refer to the article for better understanding: 🔗 https://codeanddebug.in/blog/delete-a... 📄 Full Playlist Sheet (All Questions in Order): https://docs.google.com/spreadsheets/... 🎓 Enroll in the FREE Python DSA Course: https://codeanddebug.in/course/master... 🚀 Advance Python DSA for FAANG (Zero to Hero Course): https://codeanddebug.in/course/zero-t...
