How is the height of a non-complete binary tree related to its depth?

edit

The height of a non-complete binary tree is not directly related to its depth as they represent different properties of the tree.

The height of a binary tree is defined as the maximum number of edges from the root node to a leaf node. In other words, it is the longest path from the root node to any leaf node.

The depth of a binary tree is the number of edges from the root node to a specific node in the tree. It represents the distance of a node from the root node.

Therefore, a non-complete binary tree can have varying heights and depths depending on its structure. It is possible for a non-complete binary tree to have a greater depth than its height if its structure is such that it has a very long branch from the root node to a leaf node. Similarly, it is possible for a non-complete binary tree to have a greater height than its depth if its structure is such that it has many levels of branching.
