Whatsapp Community Link : https://www.whatsapp.com/channel/0029... This is the 5th Video of our Playlist "Linked List : Popular Interview Problems". In this video we will try to solve a very good and famous Linked List problem : Linked List Cycle II | Leetcode 142 NOTE : You can easily solve Linked List Cycle-I using the same code of this problem. Just return true if there is a cycle. Share your learnings on LinkedIn, Twitter (X), Instagram, Facebook(Meta) with #codestorywithmik & feel free to tag me. I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY. We will do live coding after explanation and see if we are able to pass all the test cases. Also, please note that my Github solution link below contains both C++ as well as JAVA code.

The algorithm uses two pointers, one advancing at twice the speed of the other. If a cycle exists, the two pointers will eventually meet. Once the meeting point is identified, a second pointer is initialized from the head, and both pointers move at the same speed. The point where they meet again is the entry point of the cycle in the linked list. If no cycle is detected, the method returns null. This approach ensures efficiency in identifying cycles in linked lists with a time complexity of O(n) and constant space complexity. ╔═╦╗╔╦╗╔═╦═╦╦╦╦╗╔═╗ ║╚╣║║║╚╣╚╣╔╣╔╣║╚╣═╣ ╠╗║╚╝║║╠╗║╚╣║║║║║═╣ ╚═╩══╩═╩═╩═╩╝╚╩═╩═╝ ✨ Timelines✨ 00:00 - Introduction 1:21 - Brute Force 3:05 - Slow & Fast Pointer Approach 7:23 - Proof & intuition 13:19 - Coding it up #coding #helpajobseeker #easyrecipes #leetcode #leetcodequestionandanswers #leetcodesolution #leetcodedailychallenge #leetcodequestions #leetcodechallenge #hindi #india #coding #helpajobseeker #easyrecipes #leetcode #leetcodequestionandanswers #leetcodesolution #leetcodedailychallenge#leetcodequestions #leetcodechallenge #hindi #india #hindiexplanation #hindiexplained #easyexplaination #interview#interviewtips #interviewpreparation #interview_ds_algo #hinglish #github #design #data #google #video #instagram #facebook #leetcode #computerscience #leetcodesolutions #leetcodequestionandanswers #code #learning #dsalgo #dsa #2024 #newyear
