...the term full binary tree to denote a binary tree whose nodes have 0 or two children.) The external path length of a tree is the sum of the lengths of all root-to-external node paths in the tree. In the example, this is 2 + 2 + 3 + 3 + 2= 12. The internal... | |

The path length of a tree is the sum of the lengths...the tree shown here is 1-3 + 2-4 + 3-8 = 35. EXAMPLE 10.2 Properties of a Tree The root of the tree shown in Figure 10.3 is node a.
