+// EXERCISE: Fix the problems
+//
+//  1. Uncomment the code
+//
+//  2. Fix the problems
+//
+//  3. BONUS: Simplify the code
+//
+//
+// EXPECTED OUTPUT
+//   "Einstein and Shepard and Tesla"
+//   ["Fire" "Kafka's Revenge" "Stay Golden"]
+//   [1 2 3 5 6 7 8 9]
+// ---------------------------------------------------------

+	// -----------------------------------
+	// var books []string = [3]string{
+	// 	"Stay Golden",
+	// 	"Fire",
+	// 	"Kafka's Revenge",
+	// }
+
+	// sort.Strings(books)
+
+	// -----------------------------------
+	// // this time, do not change the nums array to a slice
+	// nums := [...]int{5,1,7,3,8,2,6,9}
+
+	// // use the slicing expression to change the nums array to a slice below
+	// sort.Ints(nums)
+
+	// -----------------------------------
+	// Here: Use the strings.Join function to join the names
+	//       (see the expected output)
+	// fmt.Printf("%q\n", names)
+
+	// fmt.Printf("%q\n", books)
+	// fmt.Printf("%d\n", nums)
