--description--

How many 18-digit numbers n (without leading zeros) are there such that no digit occurs more than three times in n?

--hints--

numbersWithRepeatedDigits() should return 227485267000992000.

assert.strictEqual(numbersWithRepeatedDigits(), 227485267000992000);

--seed--

--seed-contents--

function numbersWithRepeatedDigits() {

  return true;
}

numbersWithRepeatedDigits();
