In this competition, European clubs are divided into 8 groups of 4 teams. In group stage, teams are ranked according to some specific rules. For example Team A will be ranked above Team B if: + Team A has more points than Team B. + If their points are equal, Team A has higher goal difference than Team B. + In case of tie in all previous cases, Team A has scored more goals than Team B. + In case of tie in all previous cases, Team A has scored more Away Scored Goals than Team B. It is guaranteed that there won’t be a tie after these rules. Your task is to write a program to determine the group leaders (top 2 teams of each group) based on their results. # ورودی The input is describing 12 games which are played between teams of a group. Each line describes a game and its result. The length of each line doesn’t exceed 25.
