Solution: Linked List Cycle IV
Explore how to detect and eliminate cycles in a singly linked list using the fast and slow pointer technique known as Floyd’s Cycle Detection. Learn to identify the cycle’s start node, break the cycle in-place, and restore the list’s linear structure efficiently with O(n) time and O(1) space complexity.

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.
