Instructions

Write a function, ActiveBits, that returns the number of active bits (bits with the value 1) in the binary representation of an integer number.

Expected function

func ActiveBits(n int) int {

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
	"piscine"
)

func main() {
	fmt.Println(piscine.ActiveBits(7))
}

And its output :

$ go run .

$
