Solution: Linked List Cycle IV
Explore detecting and removing cycles in singly linked lists using the fast and slow pointers method. This lesson helps you understand Floyd's cycle detection algorithm, identify the cycle's start, and modify the list to remove loops, preserving the original order. You'll gain insight into efficient cycle handling with O(n) time and O(1) space complexities.
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.
