我们希望平铺一个长度是其宽度两倍的矩形。设T（0）为由单个矩形组成的平铺。对于n> 0，通过以下列方式替换所有瓦片，从T（n-1）获得T（n）：
|
||
|
||
以下动画演示了从0到5的n的倾斜T（n）：
|
||
|
||
设f（n）是四个瓦片在T（n）中相交的点数。例如，f（1）= 0，f（4）= 82并且f（109）mod 177 = 126897180。
|
||
|
||
找到f（10k）为k = 1018，给出你的答案模数为177。

`euler405()`应返回237696125。
|
||
|
||
```js
|
||
assert.strictEqual(euler405(), 237696125);
|
||
```
