--description--

An integer is called eleven-free if its decimal expansion does not contain any substring representing a power of 11 except 1.

For example, 2404 and 13431 are eleven-free, while 911 and 4121331 are not.

Let E(n) be the nth positive eleven-free integer. For example, E(3) = 3, E(200) = 213 and E(500 000) = 531563.

Find E(1018).

--hints--

euler442() should return 1295552661530920200.

assert.strictEqual(euler442(), 1295552661530920200);

function euler442() {

  return true;
}

euler442();
