Hi @administrators, I used the same code for Golang from the top rated solution in Java, but I'm getting TLE at input 13. Can you guys take a look? Thanks

```
func findStrobogrammatic(n int) []string {
return helper(n, n)
}
func helper(n int, m int) []string {
if n == 0 {return []string{""} }
if n == 1 {return []string{"0", "1", "8"} }
list := helper(n - 2, m)
res := make([]string, 0)
for i := 0; i < len(list); i++ {
s := list[i]
if n != m {
res = append(res,"0" + s + "0")
}
res = append(res, "1" + s + "1")
res = append(res, "6" + s + "9")
res = append(res, "8" + s + "8")
res = append(res, "9" + s + "6")
}
return res
}
```
