+// EXERCISE: Compare the slices
+//
+//  1. Split the namesA string and get a slice
+//
+//  2. Sort all the slices
+//
+//  3. Compare whether the slices are equal or not
+//
+//
+// EXPECTED OUTPUT
+//
+//   They are equal.
+//
+//
+// HINTS
+//
+//   1. strings.Split function splits a string and
+//      returns a string slice
+//
+//   2. Comparing slices: First check whether their length
+//      are the same or not; only then compare them.
+//
