![Write a java program to find the Preorder traversal of the binary search tree given in example.
Description :
Binary search tree (BST)
It is a binary tree data structure which has the following properties:
The left subtree of a node contains only nodes with keys less than the node's key.
The right subtree of a node contains only nodes with keys greater than the node's key.
Both the left and right subtrees must also be binary search trees
Example for BST is

• If the value of the new element
• is equal to the value of the current node, perform no action.
• If the value of the new element is less than the value of the current node,
proceed to the left subtree (left child) of the node. If null, insert the node as a left child the parent.
• If the value of the new element is greater than the value of the current node, proceed to the right subtree (right|
child) of the node. If null, insert the node as a left child of the parent.
