Explore how to sort a linked list by applying an optimal algorithm that runs in O(n logn) time and uses O(log n) space. This lesson helps you understand the problem constraints and practice implementing an efficient linked list sorting solution.
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
Let’s take a moment to make sure you’ve correctly understood the problem. The quiz below helps you check if you’re solving the correct problem:
