## Instructions
|
||
|
|
|
||
|
|
Write a [program](TODO-LINK) that is called `doop`.
|
||
|
|
|
||
|
|
The program has to be used with three arguments:
|
||
|
|
|
||
|
|
- A value
|
||
|
|
- An operator
|
||
|
|
- Another value
|
||
|
|
|
||
|
|
In case of an invalid entry the programs prints `0`.
|
||
|
|
|
||
|
|
In case of an invalid number of arguments the program prints nothing.
|
||
|
|
|
||
|
|
`fmt.Print` is authorized.
|
||
|
|
|
||
|
|
