Strengths:

• The solutions are correct and handle edge cases well.
• The code is clean, readable, and follows good practices.
• The use of backtracking is appropriate and effectively implemented.

Areas for Improvement:

• For combinationSum, consider sorting the candidates first to potentially optimize the solution by skipping unnecessary recursive calls when the remaining target is less than the current candidate.
• The time complexity analysis for combinationSum could be more precise. It should account for the fact that each candidate can be chosen multiple times.
• Adding more detailed comments explaining the logic, especially for the addOperators solution, would be beneficial for understanding the more complex parts of the code.
