Examine the BST below, and recall that a tree is just an acyclic (and, in this
case, undirected) graph. Let's say we start at node 12 and want to determine if
a path exists to node 29. List the order in which our method will visit the
nodes of the tree, assuming a) we are using depth-first search (DFS), b) our
method visits the left subtree before it visits the right subtree, and c) our
method terminates when we reach node 29.
NOTE 1: This question is asking you for a single sequence of nodes that meet
all three criteria. It is NOT asking for three separate sequences (one for each
criterion).
NOTE 2: You do not have to list any nodes to which you "return" during your
traversal. No node in your sequence should be listed more than once.

2. We are given a complete binary tree with height h and n nodes. The link between a node and its left child is labeled as 0 and the link between a node and its right child is labeled as 1. A path from the root to each external node at the last level can be labeled by an h-tuple (X1, X2, ..., xh) of 1s and Os that lie on its links. See the following example: 0 0 1 1 0 0 1 0 (0,0,0) (0,1,1)

Let T be an arbitrary splay tree storing n elements A1, A2, . An, where A1 ≤ A2 ≤ . . . ≤ An. We perform n search operations in T, and the ith search operation looks for element Ai. That is, we search for items A1, A2, . . . , An one by one. What will T look like after all these n operations are performed? For example, what will the shape of the tree be like? Which node stores A1, which node stores A2, etc.? Prove the answer you gave for formally. Your proof should work no matter what the shape of T was like before these operations.
