# Product of factorials

The Factorial of an integer

`n`

is defined as:Given a positive integer

`n`

, you are asked to compute the product of factorials from `1`

to `n`

. So, you’re asked to compute the product of factorials:The input contains a single integer

`n`

. The program should print a single integer - the product of factorials from

`1`

to `n`
