Write a program using C++ to implement the three disk-arm scheduling algorithms. Write a driver program that generates a sequence of cylinder numbers (0–999) at random, runs the three algorithms for this sequence and prints out the total distance (number of cylin-ders) the arm needs to traverse in the three algorithms. Please add comments to understand the program .
