✅ОТВЕТ: ```Creating A Creating B Creating X Dropping A Midpoint Dropping B Dropping X ```
1. Создание: Tracer::new("A") → Creating A 2. mem::replace(...): Creating XDropping A 3. println!("Midpoint"): Midpoint 4. Drop поля: B, затем X Этот код демонстрирует поведение Drop при замене полей структуры в Rust через std::mem::replace.

Mr. Durov launched Telegram in late 2013 with his brother, Nikolai, just months before he was pushed out of VK, the Russian social-media platform he founded.
