# --description--

How many 20 digit numbers $n$ (without any leading zero) exist such that no three consecutive digits of $n$ have a sum greater than 9?

# --hints--

`consecutiveDigitsSum()` should return `378158756814587`.

```js
assert.strictEqual(consecutiveDigitsSum(), 378158756814587);
```

# --seed--

## --seed-contents--

```js
function consecutiveDigitsSum() {

  return true;
}

consecutiveDigitsSum();
```

# --solutions--

```js
// solution required
```
