Playlist Features: Reverse and Undo — C++ Fundamentals

Context

You’re building playlist features for a music app. You’re given the function print_playlist to display a playlist’s contents.

Task

Your task is to write two functions:

reverse_playlist takes a playlist and returns a new playlist with the songs in reverse order. The original playlist must remain unchanged.
remove_last_added takes a playlist and removes the most recently added song (to undo a song added by mistake). If the playlist is empty, it should do nothing.

Expected output

Given a playlist:

Calling reverse_playlist should return a new playlist:

Calling remove_last_added on the original playlist should reduce it to:
```
"Sound of Silence", "Blowin' in the Wind"
```
