WebThe time complexity of the above solution is O(n), where n is the total number of nodes in the linked list. The auxiliary space required by the program is O(n).. 2. Floyd’s Cycle Detection Algorithm. Floyd’s cycle detection algorithm is a pointer algorithm that uses only two pointers, which move through the sequence at different speeds. WebTo 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. 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.
