Consider a binary tree. The POSTORDER traversal of the tree is 19, 12, 26, 31, 23, 49, 57, 63, 58, 54, 35 and the INORDER traversal 12, 19, 23, 26, 31, 35, 49, 54, 57, 58, 63. If the height of the root node is 0 then what is the height of the binary tree?

Even though we've drawn the nodes to resemble a tree (for conceptual understanding), the actual nodes can be anywhere in the heap. We have included memory addresses to clarify. 0.16 Exercise: Draw the rest of the tree on the heap, making up memory addresses where needed. Next, trace the execution of recursiveSearch () in searching for "5" in this tree. At each call to recursiveSearch () draw the memory diagram, paying close attention to the stack (and therefore method parameters). 3.
