Cycle detection and removal in linked list

WebApr 19, 2010 · You can make use of Floyd's cycle-finding algorithm, also known as tortoise and hare algorithm. The idea is to have two references to the list and move them at different speeds. Move one forward by 1 node and the other by 2 nodes. If the linked list has a loop they will definitely meet. WebSep 9, 2024 · Detect loop in a linked list. Find the first node of the loop in a linked list. Check linked list with a loop is palindrome or not. Make a loop at the kth position in a linked list. Find the length of the loop in a linked list. Remove every kth node of the linked list. Remove duplicates from a sorted linked list using recursion.

WebJul 10, 2016 · Detect and Remove Loop in a Linked List We’ll first use Floyd algorithm for this purpose. Detect a Loop Point slow and fast pointer to the first node where head is pointing to. Continue to move slow pointer by one node ( slow = slow->next) and fast pointer by two nodes ( fast = fast->next->next ). WebAug 29, 2024 · Using Floyd's cycle detection algorithm allows us to detect and remove a loop from the linked list without using any extra space. To find the starting point of the loop (so that we can delete the link between the starting and the ending node of the loop to remove the cycle), we can do the following.
