Odd Even Linked List | Group Odd & Even Indexed Nodes| Optimal Linked List Solution |Java Python C++

In this video, we'll solve the Odd Even Linked List problem using the Optimal In-Place Approach. We'll rearrange the linked list by grouping all odd-indexed nodes together followed by all even-indexed nodes while maintaining their original relative order. 🔹 Understand the Odd Even Linked List Problem 🔹 Intuition Behind the In-Place Solution 🔹 Step-by-Step Dry Run 🔹 Pointer Manipulation Explained 🔹 Handle Edge Cases 🔹 Time & Space Complexity Analysis 🔹 Interview Tips and Common Mistakes This is one of the most frequently asked Linked List interview problems and helps you master pointer manipulation without using any extra space.
