### Instructions
|
||
|
|
|
||
|
|
Write a function that takes a `string` as an argument and returns the letter `G` followed by a newline `\n` if the argument length is more than 3, otherwise returns `Invalid Input` followed by a newline `\n`.
|
||
|
|
|
||
|
|
- If it's an empty string return `G` followed by a newline `\n`.
|
||
|
|
|
||
|
|
### Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func PrintIfNot(str string) string {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible program to test your function:
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
|
||
|
|
"piscine"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
fmt.Print(piscine.PrintIf("abcdefz"))
|
||
|
|
fmt.Print(piscine.PrintIf("abc"))
|
||
|
|
fmt.Print(piscine.PrintIf(""))
|
||
|
|
fmt.Print(piscine.PrintIf("14"))
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output:
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ go run . | cat -e
|
||
|
|
G$
|
||
|
|
Invalid Output$
|
||
|
|
G$
|
||
|
|
Invalid Output$
|
||
|
|
```
