Acomplete traversal of an n node binary tree is a( "operation if visiting a node is o(1)for the iterative implementation
a. o(1)
b. o(n)
c. o(logn)
d. o(n2)

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.
