Now, you want to play a game, inspired by Werewolf, with a group of your friends. A Player can either be a Werewolf, or a Villager. In this game, you can have 4 or more players. The first 2 players are automatically designated to be Werewolves, while everyone else is assigned to be a Villager. One play of the game involves all of the players voting for a player who they believe to be a Werewolf; in this implementation, all players, except yourself, arbitrarily vote for themselves. At the end of each play, the player with the most votes is removed from the game. Each play of the game alternates between daytime and nighttime. If it is nighttime, only votes by werewolves count.
The game ends when there are no werewolves left, which means the villagers won, or when there are more werewolves than villagers, which means the werewolves have won.
However, there are bugs in the code for the game! Read through the code and fix all of the bugs so that the game can work properly. As hint, there are at least four bugs in the code! For this lab there is a hidden test. In other words, we will be running a test against your code that you don't have access to, so make sure to be thorough! You should not need to add any lines - only edit existing lines.
