Strengths:

• The solution is correct and handles all edge cases.
• The code is well-commented and easy to understand.
• The time and space complexity are optimal.
• The use of ArrayList is appropriate for dynamic resizing.

Areas for Improvement:

• The solution could benefit from a more concise way to initialize the row list. For example, using new ArrayList<>(i + 1) is good, but the student could also consider using Arrays.asList(1) for the first row to make it slightly more readable.
• The variable name temp could be more descriptive, such as prevRow to indicate it's the previous row in the triangle.
• The student could add a brief comment explaining why the space complexity is O(n^2) for clarity.
