This problem is about reversing a linked list. Given a linked list, the goal is to reverse the order of the nodes in the list. For example, if the input list is 1 -> 2 -> 3 -> 4 -> 5, the output should be 5 -> 4 -> 3 -> 2 -> 1.
The candidate's solution is correct and uses a stack to reverse the order of the nodes in the list. The time complexity of the solution is O(n) and the space complexity is O(n).
