package tutorial_3_5;
import java.util.*;

public class HanoiTower {

public static void main(String[] args) {
// TODO Auto-generated method stub

@SuppressWarnings("resource")
Scanner sc=new Scanner(System.in);
int n;
System.out.println("Please enter the number of your dished(Hanoi Tower):");
n=sc.nextInt();
System.out.println("The number of the times you need to move the dishes is:"+new HanoiTower().hanoiTower(n));

}

public int hanoiTower(int n)
{if(n==1) return 1;
else return hanoiTower(n-1)*2+1;
}

}
