• Strengths:
  • Both solutions correctly implement the problems using backtracking.
  • The code is well-structured and readable.
  • The handling of edge cases (like leading zeros in Problem 2) is well-done.
• Areas for Improvement:
  • For Problem 1, consider using a single list and backtracking (appending and popping) instead of creating copies to improve efficiency.
  • For Problem 2, add comments to explain the multiplication logic and the handling of leading zeros for better clarity.
  • Consider adding more descriptive variable names (e.g., sofar could be current_expr in Problem 2).
