Question

In Java, which comparison about Binary Tree Traversals is accurate?

  1. There is no practical difference in behavior, performance, or API design when Binary Tree Traversals is involved.
  2. The oldest option related to Binary Tree Traversals is always the right production choice regardless of context.
  3. Depth-first traversals follow subtree structure closely, while level-order traversal processes nodes breadth by breadth.
  4. Differences around Binary Tree Traversals are mostly cosmetic, so correctness and maintainability do not change.

Hint

Focus on the behavior or tradeoff, not just the keyword.

Answer and rationale

Correct answer: C. Depth-first traversals follow subtree structure closely, while level-order traversal processes nodes breadth by breadth.

Depth-first traversals follow subtree structure closely, while level-order traversal processes nodes breadth by breadth. This is the comparison that usually separates memorization from understanding.
