   Given the head of a singly linked list, the task is to check if the linked list has a loop. A loop means that the last node of the linked list is connected back to a node in the same list. So if the next of the last node is null. then there is no loop.

   How to detect a loop in a linked list?

   • The solution to solve this problem is: First, we detect the loop in the linked list. Detect the start node of the loop. First, we will detect a loop in the linked list. To understand this, we will look at the algorithm for detecting a loop. Step 1: First, we will initialize two pointers, i.e., S as a slow pointer and F as a fast pointer.

   What happens if a loop exists in a linked list?

   • If a loop exists in the linked list, the fast and slow pointers are bound to meet at some point. Algorithm: Initialise two pointers, fast and slow to the head of the linked list. Traverse through the linked list until the fast pointer doesn’t reach the end of the linked list.

   What is a loop in a linked list?

   • A loop in a linked list is a condition that occurs when the linked list does not have any end. When the loop exists in the linked list, the last pointer does not point to the Null as observed in the singly linked list or doubly linked list and to the head of the linked list observed in the circular linked list.

   How do I know if a linked list has a cycle?

   • Linked List Cycle II - Given the head of a linked list, return the node where the cycle begins. If there is no cycle, return null. There is a cycle in a linked list if there is some node in the list that can be reached again by continuously following the next pointer.
