Learn how to solve the Partition List problem efficiently! 🚀

In this video, we break down the logic for partitioning a linked list around a value `x` such that all nodes less than `x` come before nodes greater than or equal to `x`, while preserving the original relative order.

We cover:
✅ The "Two Dummy Heads" strategy
✅ Visualizing pointer manipulation
✅ Avoiding infinite cycles (common pitfall!)
✅ Time and Space complexity analysis

This is a classic interview question found on platforms like LeetCode (Problem 86). Perfect for beginners learning data structures.
