Question

Use the traversal method  (pre order )  draw the bst  (binary search tree ) of the number . Don't code . Just show the implementation in drawing 

This question regards tree traversal.
Consider the function below that implements a traversal of a binary tree.
(defstruct (tree-node (: conc-name nil))
key lb rb)
(defun traverse (node)
(when node
(format t"-a " (key node))
(traverse (1b node))
(traverse (rb node))))
Suppose the symbol *tree* is bound to the root node of a Binary Search
Tree (BST) containing integer numbers.
Consider the numbers printed by the following call to function TRAVERSE
RTL-USER> (traverse *tree*)
99
34
90
43
3
11
91
64
72
19
What you are asked:
• Write again the sequence of numbers printed by TRAVERSE (this will
facilitate marking your answer, in case you write it on a separate paper).
. Draw the BST. You don't have to show it in lisp notation.
