 */

public static void main(String[] args) {
	
	
	sc = new Scanner(System.in);
	int n = sc.nextInt();
	
	int row = 1;
	int cst = n;
	int spc = 1;
	
	while (row <= n) {
		
		if(row == 1 || row == n) {
			int st = 1;
			while(st <= cst) {
			System.out.print("*");
			st++;
			}
		}else {
			
			int st = 1;
			while(st <= cst) {
			System.out.print("*");
			st++;
			}
			
			int sp = 1;
			while( sp <= spc ) {
				System.out.print(" ");
				sp++;
			}
			
		}
	}
	
	cst++;
	spc= spc+2;
	row++;
}
