从1开始并以下列方式逆时针旋转，形成边长为7的方形螺旋。 37 36 35 34 33 32 31 38 17 16 15 14 13 30 39 18 5 4 3 12 29 40 19 6 1 2 11 28 41 20 7 8 9 10 27 42 21 22 23 24 25 2643 44 45 46 47 48 49这是有趣的是，奇数方块位于右下角，但更有意思的是沿着两条对角线的13个数字中有8个是素数;也就是说，比例为8 /13≈62％。如果在上面的螺旋周围缠绕一个完整的新层，则将形成具有边长9的方形螺旋。如果继续这个过程，那么沿着两条对角线的素数比首先低于10％的方形螺旋的边长是多少？

`euler58()`应返回26241。
|
||
|
||
```js
|
||
assert.strictEqual(euler58(), 26241);
|
||
```
