# --description--
|
||
|
||
如果存在一条直线恰好经过S中的两个点,则一组晶格点S称为钛酸组。
|
||
|
||
泰坦尼克集的示例是S = {(0,0),(0,1),(0,2),(1,1),(2,0),(1,0)},其中 通过(0,1)和(2,0)的通道不会通过S中的任何其他点。
|
||
|
||
另一方面,集合{(0,0),(1,1),(2,2),(4,4)}不是泰坦尼克号集合,因为穿过集合中任意两点的线也经过 通过其他两个。
|
||
|
||
对于任何正整数N,令T(N)为每个点(x,y)都满足0≤x,y≤N的钛酸集合S的数量。 可以验证T(1)= 11,T(2)= 494,T(4)= 33554178,T(111)mod 108 = 13500401和T(105)mod 108 = 63259062。
|
||
|
||
找出T(1011)mod 108。

`euler415()`应该返回55859742。
|
||
|
||
```js
|
||
assert.strictEqual(euler415(), 55859742);
|
||
```
|

function euler415() {

return true;

}
|

euler415();
