// HINTS

|
|
// ONLY READ THIS IF YOU GET STUCK
|
|
//
|
|
// Below, []string means string slice, []byte means byte slice.
|
|
//
|
|
// + You can use the os.Args[1:] to get a []string
|
|
// + Then you can sort it using sort.Strings
|
|
// + Use ioutil.WriteFile to write to a file.
|
|
// + But you need to convert []string to []byte to be able to
|
|
// write it to a file using the ioutil.WriteFile.
|
|
// + To do that, create a new []byte and append the elements of your
|
|
// []string.
