Nettet9. mar. 2024 · Approach: Create a map that will store the visited node in the linked list. Traverse the linked list and do the following: Check whether the current node is present on the map or not. If the current node is not present in the map then, insert the current node into the map. If the Node is present in the map, the loop in a linked list is detected. NettetStep 1: First, we will initialize two pointers, i.e., S as a slow pointer and F as a fast pointer. Initially, both the pointers point to the first node in the linked list. Step 2: Move the 'S' pointer one node at a time while move the 'F' pointer two nodes at a time.

Nettet2. aug. 2009 · This algorithm is used to find a loop in a linked list. It uses two pointers one moving twice as fast as the other one.
