• The student's solution for reversing a linked list is excellent. It correctly implements the iterative approach with optimal time and space complexity.
• The code is clean and easy to understand, with good variable naming and logical flow.
• One minor suggestion: In C++, it's more idiomatic to use nullptr instead of NULL for null pointers, as the student has done in some parts of the code. Consistency in using nullptr throughout would be slightly better.
• The student has also provided solutions for other linked list problems (detecting a cycle and removing the nth node from the end), which are correct and well-implemented, showing a good understanding of linked list operations.
