	{
		if (i == 1 || i == rows || i == rows * 2 - 1)
		{
			for (int j = 1; j <= rows; j++)
			{
				if (j == 1 || j == rows)
				{
					printf(" ");
				}
				else
				{
					printf("*");
				}
			}
		}
		else
		{
			for (int k = 1; k <= rows; k++)
			{
				if (k == 1 || k == rows)
				{
					printf("*");
