Solution: Linked List Cycle IV
Understand how to detect and eliminate cycles in singly linked lists using the fast and slow pointers technique. This lesson guides you through Floyd's Cycle Detection algorithm, allowing you to identify cycle presence, find the cycle's entry node, and break the cycle while maintaining the list's original order. You will learn to implement this in place with optimal time and constant space complexity.
We'll cover the following...
Statement
Given the head of a singly linked list, implement a function to detect and remove any cycle present in the list. A cycle occurs when a node's next pointer links back to a previous node, forming a loop within the list.
The function must modify the linked list in place, ensuring it remains acyclic while preserving the original node order. If no cycle is found, return the linked list as is.
