package main
// ---------------------------------------------------------
// EXERCISE: Sort and write items to a file
//
// 1. Get arguments from command-line
//
// 2. Sort them
//
// 3. Write the sorted slice to a file
//
//
// EXPECTED OUTPUT
//
// go run main.go
// Send me some items and I will sort them
//
// go run main.go orange banana apple
//
// cat sorted.txt
// apple
// banana
// orange
//
//
// HINTS
//
// + REMEMBER: os.Args is a []string
//
// + String slices are sortable 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.
