Strengths:

• The student has implemented two different approaches for the Combination Sum problem, showing a good understanding of backtracking.
• The code is well-commented, explaining the time and space complexity and the approach.
• The use of backtracking with a single list and removal of the last element is efficient and avoids deep copies.

Areas for Improvement:

• The combinationRecursion method uses a for loop that might be less efficient than the 0/1 recursion approach. However, since it is not the primary method, it is acceptable.
• The student included an unrelated solution for "Expression Add Operators" in the same submission. For future submissions, ensure that only the solution for the assigned problem is included to avoid confusion.

Overall, the solution for Combination Sum is correct and efficient.
