### Instructions
|
|
|
|
|
|
|
|
|
|
Write a program that is called `doop`.
|
|
|
|
|
|
|
|
|
|
The program has to be used with three arguments:
|
|
|
|
|
|
|
|
|
|
- A value
|
|
|
|
|
- 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
|
|
|
|
|
|

|
$ 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
|
|
|
|
|
$ go run . 1 "*" 1
|
|
|
|
|
1
|
|
|
