Solution: Linked List Cycle IV
Explore how to detect and remove cycles in singly linked lists by applying the fast and slow pointers technique. This lesson guides you through Floyd’s cycle detection algorithm step-by-step, helping you identify cycle entry and break cycles to restore linear linked lists efficiently.

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.
