+ * Crea un juego interactivo por terminal en el que tendrás que adivinar

+ * - Tendrás 3 segundos para responder correctamente.
+ * - El juego finaliza si no se logra responder en ese tiempo.
+ * - Al finalizar el juego debes mostrar cuántos cálculos has acertado.
+ * - Cada 5 aciertos debes aumentar en uno el posible número de cifras 
+ *   de la operación (cada vez en un operando):
+ *   - Preguntas 1 a 5: X (entre 0 y 9) operación Y (entre 0 y 9)
+ *   - Preguntas 6 a 10: XX (entre 0 y 99) operación Y (entre 0 y 9)
+ *   - Preguntas 11 a 15: XX operación YY
