Sep 16, 2020 · The vertex of a binary tree is called an single child if it has a father's vertex but does not have a neighbor. The root is not considered an single child. let mark in numOnly a number of vertices in T that hold the attribute "single son ", and ‘with n we mark the total number of vertices in the T tree. i need to prove that every non-empty AVL tree has inequality n u m O …

Making this method static will allow us to handle empty (i.e., null) trees. If the tree is empty, this method will return − 1; otherwise, it will return the height stored in the tree. This method can be public. We then can modify the constructor so that it initializes the height field.
