### Problem

Write a program to find a factorial of a given number.

### Examples

6! = 720, 5! = 120, 4! = 24

### Dos

- Try to solve it in a most simple and efficient way.
- Share your codes in the comments (in any language), I'll find some bugs ๐.
- Feel free to mention if you find any bugs in my code ๐ง.
- Share some challenges in the comments, I'll solve them in my next blog post.

### Don'ts

- Never see my code before solving it on your own.

### Code

```
import math
num = 5
print(math.prod([i for i in range(1, num + 1)]))
```

I've used Python for solving this challenge, but if you want the same solution in some other languages let me know in the comments ๐.
