Strengths:

• The TwoSum solution is efficient and correct, with optimal time and space complexity.
• The code is well-commented and follows good practices, such as using descriptive variable names.
• The solution handles the problem constraints effectively.

Areas for Improvement:

• Ensure that only the relevant solution files are submitted for the given problem. The inclusion of the knapsack solution suggests a possible mix-up.
• Although not necessary, consider adding a check for null input or empty array for robustness, even though the constraints state the array length is at least 2.
• In the return statement for the edge case (which should not occur due to the problem guarantee), returning an empty array is acceptable, but you might note that the problem guarantees exactly one solution.

Overall, the TwoSum solution is excellent. The only issue is the unrelated file, which might be an oversight.

Strengths:

• Your solution for TwoSum is correct and efficient, with optimal time complexity O(n).
• The code is well-structured and readable, with good variable naming and comments.
• You successfully used a HashMap to achieve the O(n) time complexity, which is the standard efficient approach for this problem.

Areas for Improvement:

• The problem states that there is exactly one solution, so returning an empty array when no solution is found is acceptable, but you might consider returning null or throwing an exception to be explicit, though it is not required.
• Be cautious when submitting multiple files; ensure that only the relevant solution is provided for the problem being evaluated. The inclusion of the Knapsack solution might be confusing, but it does not affect the correctness of the TwoSum solution.
