Go’s sort package implements sorting for builtins and user-defined types.
We’ll look at sorting for builtins first.

	// Sort methods are specific to the builtin type;
	// here’s an example for strings. Note that sorting is in-place,
	// so it changes the given slice and doesn’t return a new one.
	strs := []string{"c", "a", "b"}
	sort.Strings(strs)
	fmt.Println("Strings:", strs)

	// An example of sorting ints.
	ints := []int{7, 2, 4}
	sort.Ints(ints)

	// We can also use sort to check if a slice is already in sorted order.
	s := sort.IntsAreSorted(ints)
	fmt.Println("Sorted: ", s)

	// Running our program prints the sorted string and int slices and true as the result of our AreSorted test.
