--description--

在一个房间里，N个椅子摆放在圆桌旁。骑士一个接一个地进入房间，随意选择一把可用的空椅子。为了拥有足够的肘部空间，骑士总是在彼此之间留下至少一把空座椅。

当没有任何合适的椅子时，确定空椅子的分数C.我们还将E（N）定义为C的期望值。我们可以验证E（4）= 1/2和E（6）= 5/9。

找到E（1018）。将答案四舍五入到小数点后十四位，形式为0.abcdefghijklmn。

--hints--

euler469()应该返回0.56766764161831。

assert.strictEqual(euler469(), 0.56766764161831);

--seed--

--seed-contents--

function euler469() {

  return true;
}

euler469();
