import java.util.*;

public class Diamond

{

public static void main(String[] args)

System.out.println("Enter the number of Rows:-");

int r= sc.nextInt();

System.out.println("##Pattern:-");

for (int a=1; a<=r; a++)

{

// $\sf\red{Printing \: space}$

for (int b=r; b>a; b--)

{

System.out.print(" ");

}

// $\sf\red{Printing \: star}$

for (int c=1; c<=(a * 2) -1; c++)

{

System.out.print("*");

}

System.out.println();

}

for (int a=r-1; a>=1; a--)

{

// $\sf\red{Printing \: space}$

for (int b=r-1; b>=a; b--)

{

System.out.print(" ");

}

// $\sf\red{Printing \: star}$

for (int c=1; c<=(a * 2) -1; c++)

{

System.out.print("*");
