Solution: Linked List Cycle IV
Understand how to apply the fast and slow pointer technique to detect and remove cycles in singly linked lists. This lesson guides you through Floyd’s Cycle Detection method to identify cycle entry points and modify the list in place, ensuring a linear structure and preserving original node order.

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.
