Instructions
Write a function that returns the square root of the int passed as parameter if that square root is a whole number. Otherwise it returns 0.
Expected function
func Sqrt(nb int) int {
}
Usage
Here is a possible program to test your function :
package main
import (
"fmt"
"piscine"
)
func main() {
fmt.Println(piscine.Sqrt(4))
fmt.Println(piscine.Sqrt(3))
}
And its output :
$ go run .
