Hi! I'm a grad student working on a research project about using large language models to automate code review. Based on your commit 6e450e8 and the changes in 0004-median-of-two-sorted-arrays/Code/1.java, my tool generated this comment:

1. Input Validation: Add checks at the beginning of the method to validate that neither nums1 nor nums2 is null:
3. if (nums1 == null || nums2 == null) {

4.    throw new IllegalArgumentException("Input arrays cannot be null");
   

5. }
7. Handling Empty Arrays: The code should handle the case where one or both of the input arrays are empty:
9. if (len1 == 0 && len2 == 0) {

10.    throw new IllegalArgumentException("Both input arrays are empty");
    

11. }
12. if (len1 == 0) {

13.    return len2 % 2 == 0 ? (nums2[len2 / 2 - 1] + nums2[len2 / 2]) / 2.0 : nums2[len2 / 2];
    

14. }
15. if (len2 == 0) {

16.    return len1 % 2 == 0 ? (nums1[len1 / 2 - 1] + nums1[len1 / 2]) / 2.0 : nums1[len1 / 2];
    

17. }
19. Boundary Conditions: Ensure that checks are in place to prevent accessing out-of-bounds indices:
21. if (count1 < len1 && count2 < len2) {

22.    // Safe to access nums1[count1] and nums2[count2]
    

23. }
25. Return Value Handling: Instead of returning Integer.MIN_VALUE, consider throwing an IllegalStateException if the method reaches a state where it cannot compute a median:
27. throw new IllegalStateException("Unexpected state reached in findMedianSortedArrays");
29. Testing Edge Cases: Ensure that the function is tested with various edge cases, including both input arrays being empty, one array being empty, and arrays of different lengths.

As part of my research, I'm trying to understand how useful these comments are in real-world development. If you have a moment, I'd be super grateful if you could quickly reply to these two yes/no questions:

1. Does this comment provide suggestions from a dimension you hadn’t considered?

2. Do you find this comment helpful?

Thanks a lot for your time and feedback! And sorry again if this message is a bother.
