快速输入方法，用空格分隔[Golang]

Question

I'm trying to take fast input through scanner.Bytes and I'm it converting to int. The problem is : input provided is single line spaced elements ( like an array ) and scanner.Bytes reads it as a whole and converts it into int. How can I use a Splitfunction on the bytes read!

func main()  {
    scanner := bufio.NewScanner(os.Stdin)
    var t int
    fmt.Scanf("%d", &t)

    for o := 0; o < t; o++ {
        scanner.Scan()
        //scanner.Split(bufio.ScanWords())
        val := toInt(scanner.Bytes())
        fmt.Println(val)
    }
}

func toInt(buf []byte) (n int) {
    for _, v := range buf {
        n = n*10 + int(v-'0')
    }
    return
}

why not just try something like

func main()  {
    scanner := bufio.NewScanner(os.Stdin)

    for scanner.Scan() {
        val, err := strconv.Atoi(scanner.Text())
        if err != nil {
            log.Fatal(err)
        }
        fmt.Println(val)
    }
}
