Solution: Linked List Cycle IV
Explore how to implement Floyd’s Cycle Detection to identify and remove cycles in a singly linked list. Understand the use of fast and slow pointers to detect loops, find cycle entry points, and restore the list to a linear structure efficiently with constant space.

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.
