## evenlength

### Instructions

Write a function that receives a slice of strings and returns a new slice with the strings in which the length is even. When the slice is empty or there are no even strings return an empty slice.

### Expected function

```go
func EvenLength(strings []string) []string {
}
```

### Usage

Here is a possible program to test your function:

```go
package main

import "fmt"

func main() {
    fmt.Println(EvenLength([]string{"Hi", "Hola", "Ola", "Ciao", "Salut", "Hallo"}))
}
```

And its output:

```console
$ go run .
[Hi Hola Ciao]
```
