Explore how to sort a linked list in ascending order by applying efficient algorithms that meet optimal time and space complexity requirements. This lesson helps you practice implementing solutions in a coding playground while reinforcing your understanding of algorithm efficiency and linked list manipulation.
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
