Linked List Cycle IV
Explore how to identify and remove cycles in singly linked lists by using the fast and slow pointers method. This lesson teaches you to modify the list in place, preserving node order while ensuring the list is acyclic. Gain practical skills for handling looped linked list scenarios common in coding interviews.
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
