Question

Design and Implement an Object-Oriented Music Player in Go

You are asked to design and implement a small, object-oriented music management and playback system in Go.

Requirements

Core domain types:
- Song
- Playlist
- Player
Playlist features:
- Add/remove songs
- Reorder/move songs
- Optional deduplication toggle (prevent duplicate songs by ID)
Merging playlists:
- Merge two playlists while preserving the relative order of songs from each source
- Define and implement a duplicate-handling policy (e.g., keep-first, keep-last, keep-both)
Player controls and behavior:
- Play, pause, next, previous
- Shuffle
- Repeat modes (off, one, all)
Engineering aspects:
- Expose clear APIs and data structures
- Discuss time and space complexity of core operations
- Consider concurrency for simultaneous edits and playback; design for thread safety
- Consider persistence (saving/loading playlists)
- Outline unit tests for core behaviors

Assume a console-based player (no actual audio) where playback means managing state and current song position.
