    "os"
)

func main() {
    array := []uint64{1,5,10}
    size := len(array)
    max := array[size-1]
    obj := ef.New(max, size)

    obj.Compress(array)

    v, err := obj.Next()
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    fmt.Println(v) // 1

    obj.Next()
    fmt.Println(obj.Value()) // 5
