* feat(tools): add seed/solution restore script

* chore(curriculum): remove empty sections' markers

* chore(curriculum): add seed + solution to Chinese

* chore: remove old formatter

* fix: update getChallenges

parse translated challenges separately, without reference to the source

* chore(curriculum): add dashedName to English

* chore(curriculum): add dashedName to Chinese

* refactor: remove unused challenge property 'name'

* fix: relax dashedName requirement

* fix: stray tag

# --description--
考虑形式的二次丢番图方程x2 - Dy2 = 1例如当D = 13时x中的最小解是6492 - 13×1802 = 1.可以假设当D是正整数时没有解广场。通过在D中找到D = {2,3,5,6,7}的最小解我们得到以下结果32 - 2×22 = 1 22 - 3×12 = 192 - 5×42 = 1 52 - 6× 22 = 1 82 - 7×32 = 1因此通过考虑D中对于D≤7的最小解当D = 5时获得最大的x。在x的最小解中找到D≤1000的值其中获得x的最大值。
# --hints--
`euler66()`应返回661。
```js
assert.strictEqual(euler66(), 661);
```
# --seed--
## --seed-contents--
```js
function diophantineEquation() {
return true;
}
diophantineEquation();
```
# --solutions--
```js
// solution required
```
