How to read multiple Integer values from a single line of input in go?
问题
我正在编写一个程序，我希望允许用户在提示时输入多个整数。
例如：
输入多个整数：1 3 5 7 9 11
我希望将它们存储在一个切片中：
[1 3 5 7 9 11]
英文:
I am working on a program and I want to allow a user to enter multiple integers when prompted.
For example:
Enter multiple integers: 1 3 5 7 9 11
i want it to be stored in a slice
[1 3 5 7 9 11]

得分: 1
我找到了答案：
package mainimport ("bufio""fmt""os""strconv""strings")func numbers(s string) []int {var n []intfor _, f := range strings.Fields(s) {i, err := strconv.Atoi(f)if err == nil {n = append(n, i)}}return n}func GetInputSlice() []int {scanner := bufio.NewScanner(os.Stdin)scanner.Scan() // -------------------------------> was missing this beforereturn numbers(scanner.Text())}func main() {fmt.Println("输入整数序列：")var fullslice []intfullslice = GetInputSlice()fmt.Println("输入整数序列：", fullslice)}
请注意，我只是将代码部分翻译成了中文，其他部分保持不变。
