# --description--
Let T(m, n) be the number of the binomial coefficients iCn that are divisible by 10 for n ≤ i &lt; 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
```
