## Description

You are given the code for a binary tree implementation (including all the associated classes) and the main function that will accept two files as input: binaryTree-2000001.txt and data-2000001.txt. The binaryTree-2000001.txt contains the entries storing the structure of a binary tree of 1000000 internal nodes plus a root node as well as another 1000000 leaf nodes (a total of 2000001 nodes). Assume the root NodeID is 0 and the preorder traversal starts from the root node. The data-2000001.txt file contains the data associated with the 2000001 nodes. The code given to you has the implementation of the recursive procedure to do a preorder traversal of the binary tree and determine the vertex (nodeID) with the maximum data as well as the associated data value.

You could go through the recursive implementation to get an idea for finding the node with the maximum data and the associated maximum data value. The code for the Stack ADT (class Stack and class Node) is also included along with the other classes in the file given. Your task in this project will be to design and implement the code for an iterative algorithm (nonrecursive) that uses the Stack ADT to traverse the nodes of a binary tree in a preorder fashion and determine the vertex (nodeID) with the maximum data as well as the associated data value.

The iterative algorithm is to be implemented as a member function of the BinaryTree class as indicated in the code provided. The main function has the code setup to call the recursive and iterative procedures on the binary tree object (setup based on the two input files) as well as the timers setup to calculate the run times of these two procedures. After you implement the iterative algorithm, you will run the code for five trials and report the running times for both the procedures for each of the trials as well as the average value. Compare the average running times for the recursive and iterative procedures and interpret the results.
