Ответ от 4ой ChatGPT:

Let's break it down step by step:

1. Initially, there are 5 people in the room.
2. A murderer enters, making the total 6 people in the room.
3. The murderer kills 3 people.

Now, let's subtract the 3 dead people from the total:

6 people (original count) - 3 people (killed) = 3 people remaining.

So, 3 people are alive in the room (including the murderer).
