Program Plan Intro
Preorder traversal:
It process all the nodes of the tree in the following order.
- First, traverse the root node.
- Then, traverse all the nodes in the left subtree.
- Finally, traverse all the nodes in the right subtree.
Method “preorder” to print the values stored in a binary tree is as follows:
Node preorder(Node bTree)
{
//Check tree is not empty
if (tree != null)
{
//Print the root node value
System.out.print(bTree.value + " ");
//Print value of left subtree
preorder(bTree.left);
//Print value of right subtree
preorder(bTree.right);
}
}
