• Strengths:

  • The student demonstrates a strong understanding of backtracking and recursion.
  • The code is well-organized and follows best practices.
  • The student provides clear comments and explanations for each solution.
  • The use of StringBuilder in ExpressionAddOperators2.java is a good optimization.

• Areas for Improvement:

  • In CombinationSum.java, the student could consider using a more descriptive variable name than 'idx' (e.g., 'currentIndex').
  • The student could add more comments explaining the logic behind the 'tale' variable in the ExpressionAddOperators solutions, as it might not be immediately clear to all readers.
  • The student could consider adding more test cases in the main methods to demonstrate edge case handling.
