In mathematics, the factorial of a non-negative integer `n`,
denoted by `n!`, is the product of all positive integers less
than or equal to `n`. For example:

```
5! = 5 * 4 * 3 * 2 * 1 = 120
```

| n   |                n! |
| --- | ----------------: |
| 0   |                 1 |
| 1   |                 1 |
| 2   |                 2 |
| 3   |                 6 |
| 4   |                24 |
| 5   |               120 |
| 6   |               720 |
| 7   |             5 040 |
| 8   |            40 320 |
| 9   |           362 880 |
| 10  |         3 628 800 |
| 11  |        39 916 800 |
| 12  |       479 001 600 |
| 13  |     6 227 020 800 |
| 14  |    87 178 291 200 |
| 15  | 1 307 674 368 000 |
