Solution: Linked List Cycle IV
Understand how to implement the fast and slow pointers technique, also known as Floyd's Cycle Detection, to identify and remove cycles in a singly linked list. This lesson helps you modify the list in place, ensuring it remains acyclic while preserving node order, with a focus on efficiency and in-place cycle removal.
We'll cover the following...
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.
Constraints:
The number of nodes in the list is in the range
