我想通過分隔符“/”擴展一串切片。例如，擴展以下切片s := []string{"5/3","9","5/4/1","6"}應該產生單獨的切片：["5","9","5","6"] ["5","9","4","6"] ["5","9","1","6"]["3","9","5","6"] ["3","9","4","6"] ["3","9","1","6"]我幾乎被困在這里var c [][]string{}s := []string{"5/3","9","5/4/1","6"}for _, v := range s { combos := strings.Split(v, "/") for _, combo := range combos { } }

除了運行時間，您可以通過遞歸來實現。
func Perm(digits [][]string) (perm [][]string) {
if len(digits) == 0 || len(digits) == 1 {
return digits
}
nextDigits := Perm(digits[1:])
for _, digit := range digits[0] {
for _, next := range nextDigits {
cat := append([]string{digit}, next...)
perm = append(perm, cat)
}
}
return perm
}
