📝 **Question:** Implement `LRUCacheTTL` with `get/put` and a fake clock injected via the `now` parameter (default: `time.time`). For deterministic tests, pass `now=lambda: clock[0]` and advance `clock[0]` manually. Run the test scenario in the starter. 📋 Pick the right answer. 💡 **Hint:** Re-read the theory above if unsure.
