The candidate's solution correctly implements a function to check if a singly linked list is a palindrome. The candidate uses a stack to store the data from the first half of the list, then compares the data in the second half of the list to the data in the stack. If the data doesn't match, the list is not a palindrome.
The candidate's solution is complete and correctly solves the problem. The candidate's approach is sound.
