Construct Binary Tree from Inorder and Postorder Traversal (post-in.py)

Remember: The student's solution is written in Python, while the reference is in C++. Keep that in mind when comparing.

Let's begin.

VERDICT: NEEDS_IMPROVEMENT

---

Root to Leaf Sum (root-leaf.py)

Strengths:

• The code is clean and easy to read.
• The time and space complexity are optimal.
• The logic is correct.

Areas for improvement:

• Although not necessary, it's better to avoid using instance variables for recursion accumulation if possible, because it can lead to issues if the same instance is reused. However, in the context of LeetCode, it's acceptable. The alternative recursive method that returns the sum might be more elegant and avoid the use of instance variables.
• The student has commented out an __init__ method. It's not needed, so it should be removed to keep the code clean.

But these are minor points. The solution is correct.

Final

VERDICT: PASS
