Answer:
B.O(n).
Explanation:
Since the time complexity of visiting a node is O(1) in iterative implementation.So the time complexity of visiting every single node in binary tree is O(n).We can use level order traversal of a binary tree using a queue.Which can visit every node in O(n) time.Level order traversal do it in a single loop without doing any extra traversal.
Well we have SRAM(Static Random Access Memory) is faster, have a lower density but it is more expensive.
While DRAM(Dynamic Random access memory) is just the opposite.
Those are the only two, I know exist.
