- An operator, one of : `+`, `-`, `/`, `*`, `%`
- Another value
In case of an invalid operator, value, number of arguments or an overflow, the programs prints nothing.
The program has to handle the modulo and division operations by 0 as shown on the output examples below.
### Usage
```console
$ go run .
$ go run . 1 + 1 | cat -e
2
$
$ go run . hello + 1
$ go run . 1 p 1
$ go run . 1 / 0 | cat -e
No division by 0
$
$ go run . 1 % 0 | cat -e
No modulo by 0
$
$ go run . 9223372036854775807 + 1
$ go run . -9223372036854775809 - 3
$ go run . 9223372036854775807 "*" 3
