In many multiplayer online games, there$$s a $$looking for group$($lfg$)$ feature for being automatically matched with other players. Such a feature behaves like a queue: players join the queue to become part of a group. The players who join the queue first are the first to be grouped. Once their group is complete, they can be removed in groups. Here you$$ll implement a looking$-$for$-$group queue for a game where players can be one of three roles $($Defender$,$ Hunter, and Bard$)$ and each group consists of one Defender, one Hunter, and one Bard.

The following files have been given to you: $1.$ A C$++$ header file $($lfgqueue$.$h$)$ declaring the LFGQueue class. $2.$ A C$++$ header file $($player$.$h$)$ declaring the Player class. $3.$ A C$++$ header file $($player$.$cpp$)$ implementing the Player class. $4.$ A C$++$ source file $($main$.$cpp$)$ containing a main$()$ function with tests.

Create new C$++$ source file named lfgqueue.cpp that implements the classes declared in lfgqueue.h so that lfgqueue.cpp and the provided files compile into a program that runs with no failed tests. The BACK of the queue MUST be at index $0$ in the array.
