Let T be the unique binary tree that satisfies all of the following four constraints: • T contains 4 vertices • The vertex set of V {a,b,c,d} • If we traverse the tree T in in-order, we visit the vertices in the following order: (a,b,c,d) • If we traverse the tree T in post-order, we visit the vertices in the following order: (a,c,d,b) Notice that there exists one and only one binary tree satisfying all of these four constraints. Suppose we traverse the tree T in pre-order. In which order would we visit the four vertices? 1. The first vertex visited in a pre- order is 2. The second vertex visited in a pre- d order is 3. The third vertex visited in a pre- order is a b 4. The fourth vertex visited in a pre- order is > > >
