+//#47 - CALENDARIO DE ADVIENTO 
+/*
+ * EJERCICIO:
+ * ¡Cada año celebramos el aDEViento! 24 días, 24 regalos para
+ * developers. Del 1 al 24 de diciembre: https://adviento.dev
+ *
+ * Dibuja un calendario por terminal e implementa una
+ * funcionalidad para seleccionar días y mostrar regalos.
+ * - El calendario mostrará los días del 1 al 24 repartidos
+ *   en 6 columnas a modo de cuadrícula.
+ * - Cada cuadrícula correspondiente a un día tendrá un tamaño
+ *   de 4x3 caracteres, y sus bordes serán asteríscos.
+ * - Las cuadrículas dejarán un espacio entre ellas.
+ * - En el medio de cada cuadrícula aparecerá el día entre el
+ *   01 y el 24.
+ *
+ * Ejemplo de cuadrículas:
+ * **** **** ****
+ * *01* *02* *03* ...
+ * **** **** ****
+ *
+ * - El usuario seleccioná qué día quiere descubrir.
+ * - Si está sin descubrir, se le dirá que ha abierto ese día
+ *   y se mostrará de nuevo el calendario con esa cuadrícula
+ *   cubierta de asteríscos (sin mostrar el día).
+ *
+ * Ejemplo de selección del día 1
+ * **** **** ****
+ * **** *02* *03* ...
+ * **** **** ****
+ *
+ * - Si se selecciona un número ya descubierto, se le notifica
+ *   al usuario.
