Consider a football tournament where n teams participate. Each team has two football kits: for home games, and for away games. The kit for home games of the i-th team has color xi and the kit for away games of this team has color yi (xi?≠?yi).
In the tournament, each team plays exactly one home game and exactly one away game with each other team (n(n?-?1) games in total). The team, that plays the home game, traditionally plays in its home kit. The team that plays an away game plays in its away kit. However, if two teams has the kits of the same color, they cannot be distinguished. In this case the away team plays in its home kit.
calculate how many games in the described tournament each team plays in its home kit and how many games it plays in its away kit.
