在一个包含8支队伍的双循环赛制中，探讨了队伍为了确保进入半决赛至少需要赢得多少场比赛。考虑到了最不利的情况下，通过分配积分来确定每支队伍至少需要获得的胜场数。
Consider a series in which 8 teams are participating. each team plays twice with all other teams. 4 of them will go to the semi final.How many matches should a team win, so that it will ensure that it will go to semi finals.?
------------------------------------------------------------
This isn't the UEFA Champions League, and no ties are allowed. So,
56 points are distributed to 8 team. In the worst case, team0 loses all the games, he gets 0 point. team1 win two games with team0 and loses all other
games, he gets 2 points. In the same way, team2 gets 4 points, team3 gets 6 points. So there are 44 points left which can be distributed to the remaining 4 teams. So the assurance points for a team should be 11 points.
