Trees - Part 2

The video tutorial explains the concepts of depth and height in tree structures. Depth is defined as the length of the path from the root node to a specific node, while height is the number of edges in the longest path from a node to a leaf node. The tutorial also covers the height of a tree, which is the height of the root node, and discusses inner nodes and edges. Diagrams are used to aid understanding, and the video concludes with a brief introduction to binary trees.

What is the significance of the longest path when discussing the height of a node?

How do you calculate the height of a tree?

Describe the concept of an internal node.
