Question
Figure 14: A tree diagram has 9 vertices. The top vertex is d. Vertex d has three branches to vertices, f, b, and a. Vertex b branches to three vertices, i, h, and e. Vertex a branches to vertex c. Vertex c branches to vertex g.
(a) Give the order in which the vertices of the tree are visited in a post-order traversal.
(b) Give the order in which the vertices of the tree are visited in a pre-order traversal.
