Program Plan Intro
Binary tree:
- Binary tree is a hierarchical structure to represent the data. The element of tree is called as a node.
- Here, the branches are used to connect the nodes.
- Each node may have zero, one, or two children.
- A node that does not have a superior node is called the root node.
- The root node is the starting node, and it is the ancestor for all other nodes in the tree.
- A node that does not have any children is called as a leaf node or an end node.
- It is used to implement binary search trees and binary heaps.

Students have asked these similar questions
public class Node
int dataCount; // number of keys with value equal to data stored at this node
int treeSize; // number of keys stored in the subtree rooted at this node int data;
Node left;
Node right; //Get nth largest value of of subtree from the input node. Method to run in o(height)
int obtain(Node n, int n){
}
Please complete the obtain method in JAVA
In java: binary tree
Write a method called size(). This method will calculate the total number of nodes the tree has.
In java: binary tree
Write a method called findTotalParents (, this method will find all the nodes that considered to be parents with any dependency and return the total number of parents. The public method shall not take any parameters, but the private method takes a BNode as a parameter, representing the current root.
