# --description--

A 4x4 grid is filled with digits $d$, $0 ≤ d ≤ 9$.

It can be seen that in the grid

$$\begin{array}{}
  6 & 3 & 3 & 0 \\\\
  5 & 0 & 4 & 3 \\\\
  0 & 7 & 1 & 4 \\\\
  1 & 2 & 4 & 5
\end{array}$$

the sum of each row and each column has the value 12. Moreover the sum of each diagonal is also 12.

In how many ways can you fill a 4x4 grid with the digits $d$, $0 ≤ d ≤ 9$ so that each row, each column, and both diagonals have the same sum?

# --hints--

`crissCross()` should return `7130034`.

```js
assert.strictEqual(crissCross(), 7130034);
```

# --seed--

## --seed-contents--

```js
function crissCross() {

  return true;
}

crissCross();
```

# --solutions--

```js
// solution required
```
