Solution: Split a Circular Linked List
Explore the technique of splitting a circular linked list into two equal circular halves by applying the fast and slow pointer method. Understand how to identify the midpoint, break the list while preserving circular structure, and return two separate head nodes, optimizing for both time and 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 ...
