Solution: Split a Circular Linked List
Explore how to split a circular linked list into two equal halves using the fast and slow pointer strategy. Understand how to identify the midpoint, break the list correctly, and maintain the circular links for both halves. This lesson helps you implement an O(n) time and O(1) space approach to manipulate circular linked lists.
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 ...
