WebIn the above example, we have implemented a LinkedList in Java. We have used Floyd's cycle finding algorithm to check if there is a loop in LinkedList. Notice the code inside the checkLoop () method. Here, we have two variables named first and second that traverse the nodes in LinkedList. first - traverse with 2 nodes at single iteration. WebTo detect the start of the loop, consider the below algorithm. Step 1: Move 'S' to the start of the list, but 'F' would remain point to node 3. Step 2: Move 'S' and 'F' forward one node at a time until they meet. Step 3: The node where they meet is the start of the loop. Let's visualize the above algorithm for more clarity.
