Écrire une fonction qui renvoie la racine carré d'un `int` passé en paramètre as parameter si cette racine carré est un nombre entier. Autrement elle renvoie `0`.

Voici un éventuel [programme](TODO-LINK) pour tester votre fonction :
|
|
|
|
|
|
|
|
|
|
|
|
```go
|
|
|
|
|
|
package main
|
|
|
|
|
|
|
|
|
|
|
|
import (
|
|
|
|
|
|
"fmt"
|
|
|
|
|
|
piscine ".."
|
|
|
|
|
|
)
|
|
|
|
|
|
|
|
|
|
|
|
func main() {
|
|
|
|
|
|
arg1 := 4
|
|
|
|
|
|
arg2 := 3
|
|
|
|
|
|
fmt.Println(piscine.Sqrt(arg1))
|
|
|
|
|
|
fmt.Println(piscine.Sqrt(arg2))
|
|
|
|
|
|
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
Et son résultat :
|
|
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
|
student@ubuntu:~/piscine/test$ go build
|
|
|
|
|
