You are implementing a binary search tree class from scratch, which, in additionto insert, find, and delete, has a method getRandomNode() which returns a random node from the tree. All nodes should be equally likely to be chosen. Design and implement an algorithm for getRandomNode, and explain how you would implement the rest of the methods

For the below tasks, you may want to create a binary tree manually and use the same tree for all of these tasks. However, for task 6, you need two trees; hence, prepare another) NB: All the methods(1-7) as well as the main method/tester statements must be written in one class. DO NOT write a different class for each method.

You are creating a binary tree class from scratch, and one of its methods, getRandomNode(), returns a random node from the tree in addition to the standard insert, find, and delete operations. There should be an equal chance of selecting each node. Explain how you would develop the other methods after designing and implementing an algorithm for getRandomNode.

Write a method called countLeftNodes that returns the number of left children in the tree. A left child is a node that appears as the root of the left-hand subtree of another node. For example, reference tree #1 has 3 left children (the nodes storing the values 5 , 1 , and 4 ).
