### Expected function

### Usage
|
|
|
|
|
|
|
|
|
|
Here is a possible program to test your function:
|
|
|
|
|
|
|
|
|
|
```go
|
|
|
|
|
package main
|
|
|
|
|
import (
|
|
|
|
|
"piscine"
|
|
|
|
|
"fmt"
|
|
|
|
|
)
|
|
|
|
|
func main() {
|
|
|
|
|
l := piscine.EvenLength([]string{"Hi", "Hola", "Ola", "Ciao", "Salut", "Hallo"})
|
|
|
|
|
fmt.Println(l)
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
And its output:
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|

$ go run .
