### Intructions
|
|
|
|
|
|
|
|
|
|
|
|
Écrire une fonction **récursive** qui renvoie la valeur de la suite de fibonacci correspondant à l'index passé en paramètre.
|
|
|
|
|
|
|
|
|
|
|
|
La premiére valeur est à l'index `0`.
|
|
|
|
|
|
|
|
|
|
|
|
La suite débute ainsi: 0, 1, 1, 2, 3 etc...
|
|
|
|
|
|
|
|
|
|
|
|
Un index négatif renvoie `-1`.
|
|
|
|
|
|
|
|
|
|
|
|
`for` est **interdit** pour cet exercice.
|
|
|
|
|
|
|
|
|
|
|
|
### Fonction attendue
|
|
|
|
|
|
|
|
|
|
|
|
```go
|
|
|
|
|
|
package main
|
|
|
|
|
|
|
|
|
|
|
|
func Fibonacci(int index) int {
|
|
|
|
|
|
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
### Utilisation
|
|
|
|
|
|
|
|
|
|
|
|
Voici un éventuel `main.go` :
|
|
|
|
|
|
|
|
|
|
|
|
```go
|
|
|
|
|
|
package main
|
|
|
|
|
|
|
|
|
|
|
|
import (
|
|
|
|
|
|
"fmt"
|
|
|
|
|
|
piscine ".."
|
|
|
|
|
|
)
|
|
|
|
|
|
|
|
|
|
|
|
func main() {
|
|
|
|
|
|
arg1 := 4
|
|
|
|
|
|
fmt.Println(piscine.Fibonacci(arg1))
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
Et son résultat :
|
|
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
|
student@ubuntu:~/piscine/test$go build
|
|
|
|
|
|
student@ubuntu:~/piscine/test$ ./test
|
