Questions & Step-by-Step Solutions

In which scenario would you choose a linked list over an array for implementing a playlist?
  • Step 1: Understand what a playlist is. A playlist is a list of songs that you can play in order.
  • Step 2: Know what an array is. An array is a fixed-size list where you can store items like songs.
  • Step 3: Learn about a linked list. A linked list is a flexible list where each item (song) points to the next one.
  • Step 4: Consider how often you need to add or remove songs from the playlist.
  • Step 5: Realize that adding or removing songs in an array can be slow because you may need to shift other songs around.
  • Step 6: Understand that in a linked list, you can easily add or remove songs without shifting other songs, making it faster.
  • Step 7: Conclude that if you need to frequently change the playlist (add or remove songs), a linked list is a better choice.
