# --description--

|
||
考虑边长为√5，√65和√68的三角形。可以看出，该三角形具有区域9。
|
||
|
||
S（n）是所有三角形的面积之和，其边长为√（1 + b2），√（1 + c2）和√（b2 + c2）（对于正整数b和c），其积分面积不超过ñ。
|
||
|
||
示例三角形的b = 2且c = 8。
|
||
|
||
S（106）= 18018206。
|
||
|
||
找到S（1010）。

# --hints--

`euler390()`应该返回2919133642971。
|
||
|
||
```js
|
||
assert.strictEqual(euler390(), 2919133642971);
|
||
```
|
||
|

# --seed--

||
|
||
```js
|
||
function euler390() {
|
||
|
||
return true;
|
||
}
|
||
|
||
euler390();
|
