# --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
```
