sqrt

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 .
2
0
$
