A backend for a music app
Put it all together: a BeatServer class that saves whole beats, loads them, counts likes and makes remixes. Next stop: CodeBlocks Studio, where a real frontend talks to a server like this.
Challenge A:The server saves whole beats (dictionaries of drum → beats). Save "demo" as {"kick": [1, 5], "snare": [3, 7]}, load it and play_beat(res["beat"]).
