What happens when the 19 node is added to the tree?
Understand the Problem
The question is asking about the effect of adding a specific node (19) to a tree structure in terms of its diameter, height, and arrangement of nodes, requiring knowledge of tree data structures.
Answer
19 is added to maintain BST property.
If the tree is a binary search tree (BST), the node with value 19 is added at the appropriate position to maintain the BST property, meaning it will be placed where all nodes on its left are smaller and all nodes on its right are greater.
Answer for screen readers
If the tree is a binary search tree (BST), the node with value 19 is added at the appropriate position to maintain the BST property, meaning it will be placed where all nodes on its left are smaller and all nodes on its right are greater.
More Information
In a binary search tree, a new key (like 19) is added at a leaf position that maintains the order where the left children of a node are lesser and the right children are greater.
Tips
A common mistake is not checking or maintaining the BST property when inserting a new node.
