给定一个自然数n，由n开始可以依次产生半数集set(n)中的数如下。

(1) n∈set(n)；

(2) 在n的左边加上一个自然数，但该自然数不能超过最近添加的数的一半；

(3) 按此规则进行处理，直到不能再添加自然数为止。

例如，set(6)={6,16,26,126,36,136}。半数集set(6)中有6 个元素。-Given a natural number n, by n half of the start can have a set order set (n) the number is as follows. (1) n ∈ set (n)　(2) in the left side of n with a natural number, but the natural number can not exceed the number of recently added half　(3) dealt with in accordance with this rule until the natural number can no longer add up to. For example, set (6) = (6,16,26,126,36,136). Set half of set (6) in the six elements.
