According to the following C# template :

using System;

using System.Collections.Generic;

public class Dice {

protected Random rnd;

public Dice(int seed) {

rnd = new Random(seed);

}

public virtual int Next() {

return rnd.Next(1,7);

}

}

public class Program

{

public static void Main()

{

}

}

Here we have a base class called Dice.

public class Dice {

protected Random rnd;

public Dice(int seed) {

rnd = new Random(seed);

}

public virtual int Next() {

return rnd.Next(1,7);

}

}

In the following, we have created a class called FairRandom.

public class FairRandom {

private int lastNumber = 3;

private Random rnd;

public FairRandom() {

Console.WriteLine("Enter Seed Value");

string userInput = Console.ReadLine();

int seed = Convert.ToInt32(userInput);

rnd=new Random(seed);

}

public int Next() {

int num;

if (lastNumber == 6) {

num = rnd.Next(1,3);

}

else if (lastNumber == 1) {

num = rnd.Next(5,7);

}

else {

num = rnd.Next(1,7);

}

lastNumber = num;

return num;

}

}

Please copy and paste the class FairRandom into the template and update the classes so that FairRandom is a proper sub-class of Dice without any compilation errors and warnings.

Notice that FairRandom should have a custom constructor that takes in an integer random seed, and please run the program to make sure the random seed is working after you do the changes.
