Explore how to sort a linked list in ascending order efficiently. This lesson helps you implement an optimal algorithm running in O(n log n) time and O(log n) space, reinforcing your understanding of linked list manipulation and algorithm efficiency.
Statement
Given the head of a linked list, return the list after sorting it in ascending order.
Constraints:
The number of nodes in the list is in the range [0,1000].
−103≤Node.value≤103
Examples
Understand the problem
