Solution: Linked List Cycle IV
Explore how to detect and remove cycles in singly linked lists using the fast and slow pointer approach known as Floyd’s Cycle Detection. Understand how to identify cycle start points, locate the last node in loops, and restore the list to a linear form, all with efficient time and 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.
