1 Requirements

1. Design and implement an AVL Tree Node class that must support "nd-

Min", "insert" and "remove" operations.

2. Design and implement a driver (the main method) that does the following:

(a) Creates an array that contains a list of 5000 integers, in a random

order, from 0 to to 4098.

(b) AVL-insert, into the rst AVL tree that is initially empty, the num-

bers in the array sequentially from the start to the end.

(c) Initialize the second empty AVL tree.

(d) Enter a forever while loop to do the following:

i. Call "ndMin" to nd the node with the smallest value.

ii. Call "Remove" to remove the smallest value from the rst AVL

tree, and display "The process with a priority of %d is now sched-

uled to run!"

iii. For the removed value, change it to a random value between 0

and 4098.

iv. Call "Insert" to insert the removed value (now changed to a

dierent value in the previous step) to the second AVL tree, and

display "The process with a priority of %d has run out of its

timeslice!"

v. When the rst AVL tree becomes empty, display "Every process

has got a chance to run; Please press "Enter" to start the next

round!"

vi. When "Enter" is pressed, swap the two AVL trees, and continue

the loop.
