The student's solution is excellent overall. Here are some minor suggestions for improvement:

• The bucket-sort method could be slightly optimized by combining the bucket filling and summation steps into a single loop, though this is a minor optimization.
• The comments and explanations are thorough, but the student could consider adding a brief summary at the end of each method to reinforce the key takeaways.
• The test cases could be expanded to cover edge cases, such as an empty input array or an array with all elements equal to zero.
