## recursivepower
|
|
|
|
|
|
|
|
|
|
### Instructions
|
|
|
|
|
|
|
|
|
|
Écrire une fonction **récursive** qui renvoie la puissance de deux `int` passés en paramètre.
|
|
|
|
|
|
|
|
|
|
Les puissances négatives renverront `0`. Les overflows **ne doivent pas** être gérés.
|
|
|
|
|
|
|
|
|
|
`for` est **interdit** pour cet exercice.
|
|
|

|
|
|
|
|
|
```go
|
|
|
|
|
func RecursivePower(nb int, power int) int {
|
|
|
|
|
|
|
|
|
|
}
|
|
|
|
|
```

|
|
|
|
package main
|
|
|
|
|
|
|
|
|
|
import (
|
|
|
|
|
"fmt"
|
|
|
|
|
piscine ".."
|
|
|
|
|
)
|
|
|
|
|
|
|
|
|
|
func main() {
|
|
|
|
|
arg1 := 4
|
|
|
|
|
arg2 := 3
|
|
|
|
|
fmt.Println(piscine.RecursivePower(arg1, arg2))
|
|
|
|
|
}
|
|
|
|
|
```

|
|
|
|
|
|
