* 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--

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

--hints--

euler58()应返回26241。

assert.strictEqual(euler58(), 26241);

--seed--

--seed-contents--

function spiralPrimes() {

  return true;
}

spiralPrimes();
