# --description--
|
||
|
||
设n是正整数。假设坐标(x,y)=(2i mod n,3i mod n)的站点为0≤i≤2n。我们将考虑与同一站点具有相同坐标的站点。
|
||
|
||
我们希望形成从(0,0)到(n,n)的路径,使得x和y坐标永不减少。设S(n)是路径可以通过的最大站数。
|
||
|
||
例如,如果n = 22,则有11个不同的站,并且有效路径最多可以通过5个站。因此,S(22)= 5.下面举例说明了一个最佳路径的例子:
|
||
|
||
还可以证实S(123)= 14并且S(10000)= 48。
|
||
|
||
求1Σk≤30,ΣS(k5)。

`euler411()`应返回9936352。
|
||
|
||
```js
|
||
assert.strictEqual(euler411(), 9936352);
|
||
```
