Solution: Linked List Cycle IV

Explore how to implement a function that detects and removes cycles in singly linked lists using fast and slow pointers. Understand Floyd’s cycle detection algorithm to identify the cycle's start and restore the list structure in place, maintaining optimal time and space efficiency.

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.
