Hints

You can use the following slice operations to solve the exercise:

Prepends "value" to the slice:

slice = append([]string{"value"}, slice...)

Appends some part (N to M) of the same slice to itself:
go
```
slice = append(slice, slice[N:M]...)
```
Copies the last part of the slice starting from M to the first part of the slice until N:
go
```
slice = append(slice[:N], slice[M:]...)
```
