Dada la cantidad de filas y columnas, imprima la imagen especular del patrón de la esvástica.
Nota: el número de filas y columnas debe ser el mismo y un número impar. Esto generará una imagen especular perfecta del patrón de la esvástica.
Ejemplos:
Input : row = 5, col = 5
Output :
* * * *
* *
* * * * *
* *
* * * *
Input : row = 9, col = 9
Output :
* * * * * *
* *
* *
* *
* * * * * * * * *
* *
* *

* * * * * *
A continuación se muestra la implementación para imprimir la imagen especular del patrón de la esvástica.

Complejidad de tiempo: O (fila * columna), donde fila es el número de filas y col es el número de columnas en el patrón de esvástica inversa.
Complejidad espacial: O (1), ya que no estamos utilizando ningún espacio adicional.
