有序列如下:

n = 0: X

n = 1: Y

n = 2:  YX

n = 3:  YXY

n = 4:  YXYYX

n = 5:  YXYYXYXY

n = 6:  YXYYXYXYYXYYX

n = 7:  YXYYXYXYYXYYXYXYYXYXY

n = 8:  YXYYXYXYYXYYXYXYYXYXYYXYYXYXYYXYYX

n = 9:  YXYYXYXYYXYYXYXYYXYXYYXYYXYXYYXYYXYXYYXYXYYXYYXYXYYXYXY

... ...

当 n 趋于无穷,Y数量和X数量的比值是多少 :-)


另外玲兰过奖。实不能和龙叔相比,种菜除外 :-)
