Binary Trees and BSTs Consider this binary tree. (a) List the descendants of node 8. (b) List the ancestors of 1 (c) List the leaf nodes. (d) List the internal nodes. (e) What are the levels of nodes 3, 1, and 9? (f) What is the height of the tree (g) What is the height of the subtree rooted at 6? (h) Is this a full binary tree? Explain. (i) Explain how we could transform this tree to be a complete binary tree i.e., state which nodes we would move and where we would move them to
