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() {
	arg1 := 4
	arg2 := 3
	fmt.Println(piscine.Sqrt(arg1))
	fmt.Println(piscine.Sqrt(arg2))

}

And its output :
