## appendrange
### Instructions
Write a function that takes an `int` min and an `int` max as parameters. That function returns a slice of `int` with all the values between min and max.
Min is included, and max is excluded.
If min is superior or equal to max, a `nil` slice is returned.
`make` is not allowed for this exercise.
### Expected function
```go
func AppendRange(min, max int) []int {
}
```
### Usage
Here is a possible program to test your function :
```go
package main
import (
"fmt"
"piscine"
)
func main() {
fmt.Println(piscine.AppendRange(5, 10))
fmt.Println(piscine.AppendRange(10, 5))
}
```
And its output :
```console
$ go run .
[5 6 7 8 9]
[]
$
```
