### Usage
Here is a possible program to test your function :
```go
package main
import (
"fmt"
piscine ".."
)
func main() {
a := 0
b := 1
piscine.Swap(&a, &b)
fmt.Println(a)
fmt.Println(b)
}
```
And its output :
```console
student@ubuntu:~/[[ROOT]]/test$ go build
student@ubuntu:~/[[ROOT]]/test$ ./test
1
0
student@ubuntu:~/[[ROOT]]/test$
```
