Golang中,利用反射和interface就可以做到,不废话看代码

func main() {
  b := []string{"a", "b", "c", "c", "e", "f", "a", "g", "b", "b", "c"}
   sort.Strings(b)
   fmt.Println(Duplicate(b))
   

   c := []int{1, 1, 2, 4, 6, 7, 8, 4, 3, 2, 5, 6, 6, 8}
   sort.Ints(c)
   fmt.Println(Duplicate(c))
}
func Duplicate(a interface{}) (ret []interface{}) {
   va := reflect.ValueOf(a)
   for i := 0; i < va.Len(); i++ {
      if i > 0 && reflect.DeepEqual(va.Index(i-1).Interface(), va.Index(i).Interface()) {
         continue
      }
      ret = append(ret, va.Index(i).Interface())
   }
   return ret
}
