In this video, I explain LeetCode 141 – Linked List Cycle, one of the most common linked list interview problems. You’ll learn how to detect whether a linked list has a cycle using both brute-force and optimal approaches.

🔑 Covered in the video:
⚡ Brute Force / Hashing approach — why it works but isn’t optimal
⚡ Floyd’s Cycle Detection (Tortoise & Hare Algorithm) — elegant two-pointer solution
⚡ Step-by-step C++ walkthrough — simple and beginner-friendly
⚡ Time & Space Complexity analysis

This isn’t just about detecting a cycle — it’s about mastering a pointer technique you’ll use in many linked list and graph problems.
