9 . 含有有限个元素的数集,定义“元素和”如下:把集合中的各数相加;定义“交替和”如下:把集合中的数按从大到小的顺序排列,然后从最大的数开始交替地加减各数.例如{4,6,9}的元素和是4+6+9=19;交替和是9-6+4=7;而{5}的元素和与交替和都是5.
(1)写出集合{1,2,3}的所有非空子集的交替和的总和;
(2)已知集合
,根据提示解决问题.
①求集合
所有非空子集的元素和的总和;
提示:方法1:
,先求出
在集合
的非空子集中一共出现多少次,进而可求出集合
所有非空子集的元素和的总和;方法2:如果我们知道了集合{1,2,3,4,5}的所有非空子集的元素和的总和为
,可以用
表示出
的非空子集的元素和的总和,递推可求出集合
所有非空子集的元素和的总和.
