Ready for Quidditch?

Quidditch

The game of Quidditch requires seven players for a team. In order for the annual tournament at Hogwarts to take place, each of the four houses (Gryffindor, Hufflepuff, Ravenclaw, and Slytherin) needs to field their full complement of seven players, no more, no less.

Registration day for the tournament is chaotic. There is only a single Wizard staffing the registration table, and students line up all day long to sign up for the tournament.

Input

At the end of the day, a single sign-up document is created with players entered in the following format:

Harry Potter, Gryfindor
Luna Lovegood, Ravenclaw
Ignatia Wildsmith, Ravenclaw
Tom Riddle, Slytherin
Newt Scamander, Hufflepuff
...
Hermione Granger, Gryfindor
Draco Malfoy, Slytherin

The document has one player per line, with their name followed by their house (team), separated by a comma. There will only be one comma per line, but there may be one or more spaces after the comma, before the start of the house name. The house name will always end the line.

Output

Your task is to write a program that determines whether or not the tournament list is complete. If there are exactly 7 players from each team, then it should print out:

List complete, let’s play quidditch!

If the list is not complete, it should print out a single line for each team that does not meet the requirement. For example, it might print out:

Ravenclaw does not have enough players.
Hufflepuff has too many players.
