Chapter 20, Problem 23RQE
Program Plan Intro
Binary tree:
- It is a binary tree.
- It focuses on the search operation of a binary tree.
- A binary tree is a tree data structure which comes under hierarchical data structure.
- It is made of nodes that have a left child, right child and a data element.

Programming questions：typedef struct node
{ int data; struct node *left, *right;}BT;The node structure of the binary tree (BT) is shown above. There is a binary tree T, please complete the function: int degreeone(BT *T) to compute how many degree 1 node in the BT. The T is the root pointer, and the function shoule return the total number of degree 1 node.
Please implement the followings:
1. Create the binary tree with 9 nodes by using pointer-based representation. struct TreeNode { int info; TreeNode * left; TreeNode * right; }
2. Implement pre-order, in-order, and post-order traversals, and print the results of the tree (Figure 1). 2 7 5 2 6 9 5 11 4
(Figure 1 and question in image below). Please help.
IN JAVA
Write an algorithm that returns the second largest value in a binary search tree containing at least two nodes.If the largest value is in node L, the second largest value is in either the parent of node L or the largest node inL’s left subtree.
