--description--

对于正整数n令fn为n的数字在基数10中的平方和例如f3= 32 = 9f25= 22 + 52 = 4 + 25 = 29f442= 42 + 42 + 22 = 16 + 16 + 4 = 36找到所有n的总和的最后九位数0 <n <1020使得fn是一个完美的平方。

--hints--

euler171()应该返回142989277。

assert.strictEqual(euler171(), 142989277);

--seed--

--seed-contents--

function euler171() {

  return true;
}

euler171();
