I'm Impostor

“Among us!” game which became popular in this year. The game is usually played with 6-10 players where players are divided into two groups. Those are impostors (1-3 player) and crew mates(7-9) divided randomly. No one knows which player is an impostor except those who are in the impostors groups. The job of an impostor is to kill the crew mates and reduce the number of crew mates equal to the living impostors. The crew mates will try to find out who is the impostor among them with available clues and kill the impostor. To learn more about the game you can read this. (Though this is not necessary for this problem.)
