Solution: Split a Circular Linked List
Explore how to split a circular linked list into two equal halves using the fast and slow pointer approach. This lesson helps you understand the technique for identifying the midpoint, breaking the circular link, and maintaining circularity in the resulting lists. You will gain skills in efficient linked list manipulation and cycle handling essential for coding interviews.
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 ...
