Welcome to the world of Pokermon, yellow little mouse-like creatures, who absolutely love playing poker!
Yeah, right…
In the ensuing Pokermon League, there are registered Pokermon trainers, and existing trainer teams. Since there is a lot of jealousy between trainers, there are pairs of trainers who hate each other. Their hate is mutual, there are no identical pairs among these, and no trainer hates himself (the world of Pokermon is a joyful place!). Each trainer has a wish list of length teams he'd like to join. All the teams are divided into two conferences.
Your task is to divide players into teams and the teams into two conferences, so that:
- each trainer belongs to exactly one team
- no team is in both conferences
- total hate between conferences is at least
- every trainer is in a team from his wish list
Total hate between conferences is calculated as the number of pairs of trainers from teams from different conferences who hate each other.
