fmt.Scan()

ref. I thought fmt.Scan() would work fine for me, but when I think about scanning multiple values from stdin, I need a scanner to process the input string by token. (fmt.Scan() and fmt.Scanln() don't support reading the entire line.)

For example,

package main

import (
    "bufio"
    "fmt"
    "os"
    "strconv"
    "strings"
)

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

    var input string
    scanner.Scan()
    input = scanner.Text()

    var values []int

    for _, text := range strings.Fields(input) {
        num, err := strconv.Atoi(text)
        if err != nil {
            fmt.Println("Error converting input:", err)
            return
        }
        values = append(values, num)
    }

    fmt.Println("Scanned values:", values)
}

I don't feel this is the optimal way to achieve that tho. will check some code online
