This problem asks you to reverse a singly linked list. An example input is given as 1->2->3->4->5, and the expected output is 5->4->3 ->2->1.

A.I. Evaluation of the Solution

The candidate's solution correctly implements a solution to reverse a singly linked list, both iteratively and recursively. The iterative solution is more efficient, however, both solutions are correct. The candidate demonstrates a good understanding of linked lists and how to reverse them.
