// ---------------------------------------------------------
// EXERCISE: Correct the lyric
//
//  You have a slice that contains the words of Beatles'
//  legendary song: Yesterday. However, the order of the
//  words are incorrect.
//
// CURRENT OUTPUT
//
//  [all my troubles seemed so far away oh I believe in yesterday now it looks as though they are here to stay]
//
// 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]
//
//
// STEPS
//
//  INITIAL SLICE:
//    [all my troubles seemed so far away oh I believe in yesterday now it looks as though they are here to stay]
//
//
//  1. Prepend "yesterday" to the `lyric` slice.
//
//     RESULT SHOULD BE:
//     [yesterday all my troubles seemed so far away oh I believe in yesterday now it looks as though they are here to stay]
//
//
//  2. Put the words to the correct positions in the `lyric` slice.
//
//     RESULT SHOULD BE:
//     [yesterday all my troubles seemed so far away now it looks as though they are here to stay oh I believe in yesterday]
//
//
//  3. Print the `lyric` slice.
//
//
// BONUS
//
//   + Think about when does the append allocate a new backing array.
//
//   + Check whether your conclusions are correct.
//
//
// HINTS
//
//   If you get stuck, check out the hints.md file.
