--description--

设f（n）是小于109的最大正整数x，使得nx的最后9位数字形成数字x（包括前导零），或者如果不存在这样的整数则为零。

例如：

f（4）= 411728896（4411728896 = ... 490411728896）f（10）= 0 f（157）= 743757（157743757 = ... 567000743757）Σf（n），2≤n≤103= 442530011399查找Σf（n ），2≤n≤106。

--hints--

euler455()应该返回450186511399999。

assert.strictEqual(euler455(), 450186511399999);

--seed--

--seed-contents--

function euler455() {

  return true;
}

euler455();

--solutions--

// solution required
