| // 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.
