Program Plan Intro
Binary Tree Template
Program Plan:
Main.cpp:

Pythin: A binary search tree, write a function that finds and returns the median value. Assume that the class member variable. [_size] contains the number of elements in the binary search tree. What is the time complexity of your function?

C++ DATA STRUCTURES
Implement the TNode and Tree classes. The TNode class will include a data item name of type string,which will represent a person’s name. Yes, you got it right, we are going to implement a family tree!Please note that this is not a Binary Tree.
Write the methods for inserting nodes into the tree,searching for a node in the tree, and performing pre-order and post-order traversals.The insert method should take two strings as input. The second string will be added as a child node tothe parent node represented by the first string.
Hint:
The TNode class will need to have two TNode pointers in addition to the name data member:TNode *sibling will point to the next sibling of this node, and TNode *child will represent the first child ofthis node. You see two linked lists here??? Yes! You’ll need to use the linked lists
