# --description--
|
||
|
||
考虑以下形式的方程：a2 + b2 = N，0≤a≤b，a，b和N整数。
|
||
|
||
对于N = 65，有两种解决方案：a = 1，b = 8，a = 4，b = 7。我们将S（N）称为a2 + b2 = N，0≤a≤b，a，b和N整数的所有解的a的值之和。因此，S（65）= 1 + 4 = 5.找到ΣS（N），对于所有无平均N，只能被4k + 1形式的素数整除，其中4k + 1 <150。

`euler273()`应该返回2032447591196869000。
|
||
|
||
```js
|
||
assert.strictEqual(euler273(), 2032447591196869000);
|
