Assignment 5
Write a program the reads data in exactly the same format as for
assignment 4, and constructs an AVL tree
from that data. The ordering should be exactly the same as it was
for assignment 4. When the AVL tree has been constructed, you should
use the ordinary ordered binary tree printing function/method to
output the sorted data into a file called avlout.txt
Your program should take just one input from the command line, the
name of the file containing the data to be sorted, for example
a.out /home/www/class/een318/database1.txt
