        int n;

        System.out.print("Enter the number of rows: ");
        n = scanner.nextInt();

        for (int i = 1; i <= n; i++) {
            for (int j = 1; j <= n; j++) {
                if(i==1 ||i==n||j==1||j==n-i+1||i==j||j==n) {
                    System.out.print("*");
                } else {
                    System.out.print(" ");

            }
            System.out.println();
