Your solution for reversing a linked list is excellent. It is efficient, correct, and follows the standard iterative approach. Here are some points to consider:

1. Code Organization: You have included solutions for multiple problems in the same file. While this might be acceptable in some contexts, for LeetCode submissions, each problem should be in its own file. Also, the ListNode class is already provided by LeetCode, so you don't need to redefine it unless you are testing locally.

2. Edge Cases: Your solution correctly handles the case when head is null or has only one node. However, the condition if (head == null || head.next == null) return head; is redundant because the while loop would handle these cases correctly without this check. The loop would not run if head is null, and for a single node, it would set next to null and return the node. You can remove this check to make the code more concise without affecting correctness.

3. Consistency: The code is clean and follows good naming conventions. The variables prev, curr, and temp are appropriately named and make the code easy to understand.

4. Efficiency: The solution is optimal in terms of time and space complexity. No further optimizations are needed.

Overall, your solution is correct and efficient. Just be mindful of submitting only the relevant code for the problem.
