testLab03Functions.bash

#! /bin/bash

# This script test the functions of your lab03. The idea is that you create one main function for each
# BinSearchTree function that you want to test. For example, 

# a main function that tests "bool BinSearchTree::areIdentical( TreeNode *lRoot, TreeNode *aRoot );"
# mainForAreIdentical.cpp  

# a main function that tests "BinSearchTree *BinSearchTree::differenceOf( BinSearchTree *bst );""
# mainForDifference.cpp

# a main function that tests "bool BinSearchTree::iterFind( int v );"
# mainForFind.cpp

# This script iterates over all files that start with string "main" (mainForAreIdentical.cpp,
# mainForDifference.cpp, mainForFind.cpp, etc.), compiles each file with your BinSearchTree.cpp, 
# uses listOfNumbers.input (an argument to your main function) for input, run the resulting
# executable, and stores the output in a file with extension .output. Then, it compare this
# output file with ours. If there are differences, it displays them. Otherwise, it just prints "OK."
