func main() {
    a := []int{2, 1, 2, 5, 6, 3, 4, 5, 2, 3, 9}
    z := Rm_duplicate(a)
}

func Rm_duplicate(list []int) []int {
    var x []int = []int{}
    for _, i := range list {
        if len(x) == 0 {
            x = append(x, i)
        } else {
            for k, v := range x {
                if i == v {
                    break
                }
                if k == len(x)-1 {
