WebDesignating a root imposes a hierarchy on the vertices of a rooted tree, according to their distance from that root. Def 2.3. In a rooted tree, the depth or level of a vertex v is its distance from the root, i.e., the length of the unique path from the root to v. Thus, the root has depth 0. Def 2.4. Web3.
