import java.util.Scanner;

public class Pyramidissue {

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print("How big of a pyramid you want?");

int n = input.nextInt();

{

for (int i=0; i

{

for (int j=n-i; j>0; j--)

{

System.out.print("");

}

for(int j=0; j<=i; j++ )

System.out.print(" *");

System.out.println();
