Understand how to sort a linked list by applying efficient coding patterns that achieve an O(n log n) time complexity. Practice this challenge to enhance your algorithm skills and prepare for coding interviews with confidence.
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
