Strengths:

• The code is clean, well-commented, and easy to understand.
• The approach is logical and correctly solves the problem.
• The student has provided clear time and space complexity analysis.

Areas for Improvement:

• Consider using a hashing technique (like prime number multiplication) to avoid the sorting step, which would improve the time complexity to O(n * k).
• The current solution is correct but could be more efficient with a different hashing strategy.
