|
// EXERCISE: Add a newline after each sentence
|
|
//
|
|
// You have a slice that contains Beatles' awesome song:
|
|
// Yesterday. You want to add newlines after each sentence.
|
|
//
|
|
// So, create a new slice and copy every words into it. Lastly,
|
|
// after each sentence, add a newline character ('\n').
|
|
//
|
|
//
|
|
// ORIGINAL SLICE:
|
|
//
|
|
// [yesterday all my troubles seemed so far away now it looks as though they are here to stay oh I believe in yesterday]
|
|
//
|
|
// EXPECTED SLICE (NEW):
|
|
//
|
|
// [yesterday all my troubles seemed so far \n away now it looks as though they are here to stay \n oh I believe in yesterday \n]
|
|
//
|
|
//
|
|
// CURRENT OUTPUT
|
|
//
|
|
// yesterday all my troubles seemed so far away now it looks as though they are here to stay oh I believe in yesterday
|
|
//
|
|
// EXPECTED OUTPUT
|
|
//
|
|
// yesterday all my troubles seemed so far away
|
|
// now it looks as though they are here to stay
|
|
// oh I believe in yesterday
|
|
//
|
|
//
|
|
// RESTRICTIONS
|
|
//
|
|
// + Don't use `append()`, use `copy()` instead.
|
|
//
|
|
// + Don't cheat like this:
|
|
//
|
|
// fmt.Println(lyric[:8])
|
|
// fmt.Println(lyric[8:18])
|
|
// fmt.Println(lyric[18:23])
|
|
//
|
|
// + Create a new slice that contains the sentences
|
|
// with line endings.
|
|
//
|
|
//
|
|
// NOTE
|
|
//
|
|
// If the program does not work, please update your
|
|
// local copy of the prettyslice package:
|
|
//
|
|
// go get -u github.com/inancgumus/prettyslice
|
|
//
