Solution: Linked List Cycle IV
Understand how to detect and remove cycles in a singly linked list using fast and slow pointers. Learn to identify the start of a cycle, break the loop, and restore the list's linear structure with an efficient O(n) time and O(1) space algorithm.

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.
