Backtracking-1

Strengths:

• The student demonstrates a strong understanding of backtracking and recursion.
• The code is clean, well-commented, and follows best practices.
• The student correctly analyzes and states the time and space complexities.
• The inclusion of alternative solutions shows depth of understanding.

Areas for Improvement:

• While the time complexity analysis is correct, it would be beneficial to explain why it's O(2^n) or O(4^len(num)) in comments for better clarity.
• For problem2.py, the student could add comments explaining the logic behind handling the tail and calc variables, as this part might be less intuitive for readers.
• The student could consider adding more test cases or edge case handling comments to demonstrate thoroughness.
