}

OUTPUT:
Enter the no. of disks :3
 disk 1 is moved from sourcetower to destination tower
 disk 2 is moved from sourcetower to intermediatetower
 disk 1 is moved from destination tower to intermediatetower
 disk 3 is moved from sourcetower to destination tower
 disk 1 is moved from intermediatetower to sourcetower
 disk 2 is moved from intermediatetower to destination tower
 disk 1 is moved from sourcetower to destination tower
