定义:xn =(1248n mod 32323) - 16161yn =(8421n mod 30103) - 15051 Pn = {(x1,y1),(x2,y2),...,(xn,yn)}
|
||
|
||
例如,P8 = {( - 14913,-6630),( - 10161,5625),(5226,11889),(8340,-10778),(15852,-5203),( - 15165,11295),( - 1427,-14495),(12407,1060)}。
|
||
|
||
设C(n)是顶点在Pn中的三角形的数量,其中包含内部的原点。
|
||
|
||
示例:C(8)= 20 C(600)= 8950634 C(40 000)= 2666610948988
|
||
|
||
找到C(2 000 000)。

`euler456()`应返回333333208685971500。
|
||
|
||
```js
|
||
assert.strictEqual(euler456(), 333333208685971500);
|
||
```

}
|

|
||
euler456();
