The depth of a node is the number of edges from the root to the node
Question
The depth of a node is the number of edges from the root to the node
Solution
The depth of a node in a tree data structure is the number of edges from the root node to the given node. Here's how you can calculate it:
-
Start at the root node. The depth of the root node is 0 because there are no edges between the root node and itself.
-
Move to the next level of nodes (the children of the root node). The depth of these nodes is 1 because there is one edge between the root node and each of these nodes.
-
Continue this process, adding 1 to the depth for each level you move down in the tree.
-
Once you reach the node you're interested in, the number you've counted is the depth of that node.
This process assumes that you're dealing with a rooted tree, where one node is designated as the root and every edge either points away from or towards it.

The result of a depth-first search of a graph can be conveniently described in terms of a spanning tree of the vertices reached during the search. Based on this spanning tree, the edges of the original graph can be divided into three classes: forward edges, which point from a node of the tree to one of its descendants, back edges, which point from a node to one of its ancestors, and cross edges, which do neither. Sometimes tree edges, edges which belong to the spanning tree itself, are classified separately from forward edges. If the original graph is undirected then all of its edges are tree edges or back edges.
