Strengths:

• The solutions are correct and handle edge cases well.
• The code is well-commented and easy to understand.
• The use of helper functions is a good practice for recursive problems.

Areas for Improvement:

• For combinationSum, consider using backtracking (adding and removing elements from the same list) instead of creating a new list in each iteration. This would improve space efficiency.
• For addOperators, the solution is already efficient, but you could add comments to explain the tail parameter's role in multiplication for better clarity.
• Ensure consistency in variable naming (e.g., pivot vs. i in combinationSum).
