# --description--

Let T(m, n) be the number of the binomial coefficients iCn that are divisible by 10 for n ≤ i < m(i, m and n are positive integers).

You are given that T(109, 107-10) = 989697000.

Find T(1018, 1012-10).

# --hints--

`euler322()` should return 999998760323314000.

```js
assert.strictEqual(euler322(), 999998760323314000);
```

# --seed--

## --seed-contents--

```js
function euler322() {

  return true;
}

euler322();
```

# --solutions--

```js
// solution required
```
