If there is no node in tree return false. That is for each node all elements in its left sub-tree are less-or-equal to its element and all the elements in its right sub-tree are greater than its element. Thus the expected depth of any node is O log n. For each internal node all the keys in the left sub-tree are less than the keys in the node and all the keys in the right sub-tree are greater.
