[golang] Removing element from slice

slice.go

//RemoveFromSlice remove string from slice, return number of removed items
func RemoveFromSlice(slice []string, toRemove string) (removed []string, n int) {
	for _, i := range slice {
		if i != toRemove {
			removed = append(removed, i)
		} else {
			n++
		}
	}
	return
}

//RemoveNFromSliceString remove member nth from slice
func RemoveNFromSliceString(slice []string, n int64) (newSlice []string) {
	newSlice = make([]string, len(slice)-1)
	newSlice = append(slice[:n], slice[n+1:]...)
	return
}

not sure how to do the second one without allocating new slice
