--description--

对于任何正整数k分数xi / yi的有限序列ai由以下定义a1 = 1 / k且ai =xi-1 + 1/yi-1-1减少到最低项i> 1 。当ai达到某个整数n时序列停止。 当yi = 1时。定义fk= n。例如对于k = 20

1/20→2/19→3/18 = 1/6→2/5→3/4→4/3→5/2→6/1 = 6

所以f20= 6。

对于1≤k≤100f1= 1f2= 2f3= 1且Σfk3= 118937。

找Σfk3为1≤k≤2×106。

--hints--

euler343()应该返回269533451410884200。

assert.strictEqual(euler343(), 269533451410884200);

--seed--

--seed-contents--

function euler343() {

  return true;
}

euler343();
