/** 6. You are developing a music playlist management system. Implement functions that leverage closures
and higher-order functions to perform common playlist operations.
Task 1: Create a function createPlaylist that takes a playlist name as a parameter and returns a closure. This
closure should allow adding and listing songs for the given playlist.
Task 2: Create a function addSong that takes a song name and artist as parameters and adds the song to the
specified playlist. Use the closure created in TASK 1.
Task 3: Create a function listSongs that lists all the songs in a specified playlist. Use the closure created in the
Task 1 */
