Create a program that checks if a slice is empty. Find the simplest solution.
Solution
The easiest way to check if a slice is empty is to use the built-in len() function, which returns the length of a slice. If len(slice) == 0, then you know the slice is empty.
For example:
package main
import "fmt"
func main() {
r := [3]int{1, 2, 3}
if len(r) == 0 {
fmt.Println("Empty!")
