# --description--
|
||
|
||
考虑点（x，y）的集合S（r），其中整数坐标满足| x | + | y | ≤r。设O为点（0,0），C为点（r / 4，r / 4）。令N（r）为S（r）中的点B的数量，使得三角形OBC具有钝角，即最大角度α满足90°<α<180°。因此，例如，N（4）= 24并且N（8）= 100。
|
||
|
||
什么是N（1,000,000,000）？
|

# --hints--

`euler210()`应该返回1598174770174689500。
|
||
|
||
```js
|
||
assert.strictEqual(euler210(), 1598174770174689500);
|
||
```

# --seed--

function euler210() {
|

return true;
|

}
|

|
||
euler210();
