Solution: Linked List Cycle IV
Explore how to detect and remove cycles in a singly linked list using fast and slow pointers. This lesson teaches you Floyd’s Cycle Detection algorithm to find the cycle start and remove it by adjusting node pointers, ensuring the list remains acyclic without altering node order. Learn efficient traversal and maintain optimal time and space complexity.
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
