n = Integer.parseInt(new Scanner(System.in).nextLine());
System.out.print("Enter total: ");
width = Integer.parseInt(new Scanner(System.in).nextLine());
for (i = 0; i; i++)
{
System.out.print(n);
}
System.out.println();
for (i = 0; i - 2; i++)
{
System.out.print(n);
for (j = 0; j - 2; j++)
{
System.out.print(" ");
}
System.out.println(n);
}
for (i = 0; i; i++)
{
System.out.print(n);
}
System.out.println();
