Detect Starting Point of Loop in Linked List | Floyd Cycle Detection Algorithm

Detect Starting Point of Loop in Linked List | Floyd Cycle Detection Algorithm
Want to master Linked List cycle problems in DSA? In this video, you’ll learn how to detect the starting point of a loop in a linked list using both the basic approach and the optimal Floyd’s Cycle Detection Algorithm (Tortoise and Hare method).

We break down the intuition, step-by-step logic, and code implementation in C++, so you don’t just memorize — you actually understand how to solve this in interviews and competitive programming.

🚀 What you will learn:

How loops are formed in linked lists
Brute force approach to detect loop starting node
Optimal approach using Floyd’s Algorithm
Why slow and fast pointers meet
Mathematical intuition behind finding the starting point
Clean and optimized C++ implementation

💡 This is one of the most asked DSA interview questions in companies like Amazon, Google, Microsoft, etc. If you’re preparing for coding interviews or improving your problem-solving skills, this is a must-watch.

📌 Topics Covered:
Linked List, Cycle Detection, Floyd Algorithm, Two Pointer Technique, DSA Interview Questions

🎯 Perfect for:

Beginners learning DSA
Students preparing for placements
Competitive programmers
Anyone struggling with linked list problems

👉 Follow for daily DSA content and become consistent with problem solving!
