Change the towers of hanoi program so that it does the following: a)counts the number of ring moves and prints that - instead of the sequence of the moves. use a static variable count of type int to hold the number of moves. b)repeatedly prompts the user for the number of rings and reports the results, until the user enters a number less than 0

Following are the program in the Java Programming Language.

//import scanner class package

import java.util.Scanner;

//define class

public class Tower_of_Hanoi {

//define static integer variable

public static int count = 0;

//define function

public static void Permute_Arrange(int n, char x, char ax, char to) {

//set if statement

if (n == 1) {

//increament in count by 1

++count;

}

//otherwise  

else  

{

Permute_Arrange(n - 1, x, to, ax);

++count;

Permute_Arrange(n - 1, ax, x, to);

}

}

//define main function

public static void main(String[] args)  

{

//set scanner type object

Scanner sc = new Scanner(System.in);

//print message

System.out.println("Enter less than 0 to exit");

//set the while infinite loop

while(true)

{

//print message

System.out.print("Enter the number of Disks: ");

//get input from the user

int num_of_disk = sc.nextInt();

//set the if statement to break the loop

if(num_of_disk<0)

{

//exit from the loop

System.exit(0);

}

//call the function

Permute_Arrange(num_of_disk, 'A', 'B', 'C');

//print message with output

System.out.println("Total number of Disc Moves is: " + count);

count = 0;

}

}

}

Output:

Enter less than 0 to exit

Enter the number of Disks: 4

Total number of Disc Moves is: 15

Enter the number of Disks: 7

Total number of Disc Moves is: 127

Enter the number of Disks: -1

Explanation:

Here, we define a class named "Tower_of_Hanoi"

answer; i believe the correct answer is ( a expression) plz check first.good luck
