# --description--
设SA表示大小为n的集合A中的元素之和。如果对于任何两个非空的不相交子集B和C我们将其称为特殊和集合以下属性为真SB≠SC;也就是说子集的总和不能相等。如果B包含的元素多于C则SB> SC。对于这个问题我们假设给定的集合包含n个严格增加的元素并且它已经满足第二个规则。令人惊讶的是在可以从n = 4的集合中获得的25个可能的子集对中仅需要对这些对中的1个进行相等性测试第一规则。类似地当n = 7时仅需要测试966个子集对中的70个。对于n = 12可以获得多少261625个子集对需要进行相等性测试注意此问题与问题103和问题105有关。
# --hints--
`euler106()`应返回21384。
```js
assert.strictEqual(euler106(), 21384);
```
# --seed--
## --seed-contents--
```js
function euler106() {
return true;
}
euler106();
```
# --solutions--
```js
// solution required
```
