打印实心和空心菱形图案的程序

对于任何给定的数字 n，打印用星星 (*) 制成的空心和实心正方形和菱形。
例子：

Input : n = 4
Output : 
Solid Rhombus:
   ****
  ****
 ****
****

Hollow Rhombus:
   ****
  *  *
 *  *
****

1. 实心菱形：制作实心菱形有点类似于制作实心正方形，而不是每个第 i 行我们在星号前有 ni 个空格的概念：
– – – ****
– – ****
– ****
****
2. 空心菱形：空心菱形的形成使用了空心方形和实心菱形形成背后的思想。空心正方形在每第 i 行中的星星前有 ni 个空格导致形成空心菱形。
