Struggling with linked lists? 🤯 In this video, I’ll walk you through a medium-level DSA problem: "Delete all occurrences of a given key in a Doubly Linked List" using C++. 💻🔗
🔹 Problem Statement: Given a doubly linked list and a key, remove all occurrences of that key and return the updated list.
🔹 Approach: We traverse the list, remove matching nodes, and update pointers efficiently.
🔹 Time Complexity: O(N) – Efficient traversal and deletion!
🔹 Concepts Covered:
✅ Doubly Linked List Basics
✅ Node Deletion Handling
✅ Edge Cases & Optimization
📌 Code Implementation & Explanation Included!
