Solution: Linked List Cycle IV

Understand how to detect and eliminate cycles within a singly linked list using the fast and slow pointers technique. Learn Floyd’s cycle detection method to find the cycle start and remove it by modifying the list in place, ensuring the structure remains linear and efficient.

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.
