Strengths:

• The student has a good understanding of the problem and has implemented correct solutions for all three problems.
• The code is well-organized and follows best practices.
• The student uses appropriate data structures (HashMaps) to solve the problems efficiently.

Areas for Improvement:

• Remove unnecessary comments (e.g., "Time complexity O(NKlogK) and space complexity O(N*K)" in Problem1.java) as they clutter the code.
• Ensure all code lines are necessary (e.g., the commented-out line in Problem1.java should be removed).
• Consider adding brief comments to explain the logic where it might not be immediately obvious, rather than commenting every line.
