Your solution for the "Right Side View" problem is excellent. You correctly implemented a DFS approach with a modified pre-order traversal (right before left) and used the level to determine when to add the node value to the result. This is efficient and intuitive.

Strengths:

• You provided clear comments explaining your approach.
• The code is concise and easy to read.
• You handled the base case appropriately.

Areas for Improvement:

• Although your solution is correct, note that the reference solution uses BFS (level-order traversal), which is another common approach. Both DFS and BFS are acceptable, but it's good to be familiar with both.
• In the Java solution, consider adding null checks for the result list in the helper method, though it is not strictly necessary since the list is passed from the main method.
• For consistency, you might want to use the same language for both problems unless required otherwise.

Since you included an extra problem (Cousins in Binary Tree), ensure in the future to only provide the solution for the problem being evaluated unless asked for multiple. However, your solutions for that problem are also correct.
