Solution: Split a Circular Linked List
Explore the technique of splitting a circular linked list into two equal circular lists by utilizing the fast and slow pointer approach. Understand how to identify the midpoint, break the circular link, and form two separate lists while maintaining circular references. Gain insight into optimizing linked list operations with O(n) time and O(1) space complexity.
We'll cover the following...
Statement
Given a circular linked list, list, of positive integers, split it into two circular linked lists. The first circular linked list should contain the first half of the nodes (exactly ⌈list.length / 2⌉ nodes) in the same order they appeared in the original list, while the second circular linked list should include the remaining nodes in the same order.
Return an array, answer, of length 2, where:
answer[0]is the head of the circular linked list ...
