WebThere are several ways we can remove a loop in a linked list. Let’s discuss this in detail. How to find a loop in a linked list Approach 1: Floyd’s cycle-finding algorithm. The first step in diagnosing the problem is to detect if the linked list indeed has a loop. And the quickest way to do this is by using Floyd’s cycle-finding algorithm. WebMay 23, 2024 · Detecting a Cycle. Let's now explore a couple of algorithms for detecting cycles in linked lists. 2.1. Brute Force – O (n^2) Time Complexity. With this algorithm, we traverse the list using two nested loops. In the outer loop, we traverse one-by-one. In the inner loop, we start from the head and traverse as many nodes as traversed by outer ...
