Linked List Cycle 2 (LeetCode 142) | Full solution with mathematical proof | Study Algorithms

Given a single linked list that contains a loop, find the node where the cycle starts. A very famous problem and an extension of detecting the loop. Using a slow pointer and fast pointer, can help to determine the meeting point. This video gives a mathematical proof on how the pointers meet at the start of loop. All along with diagrams and a dry-run of code in JAVA.
