Solution: Split a Circular Linked List
Understand how to split a circular linked list into two separate circular lists by using the fast and slow pointer approach. This lesson guides you through finding the midpoint and breaking the list correctly, maintaining circular links for both halves. Learn the method's logic, step-by-step process, and analyze its time and space complexity for optimal performance in 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 ...
