Practice Coding with the exercise "EUROPEAN RUGBY CHAMPIONS CUP RANKING"

Statement

Goal

Every year the best rugby teams in Europe compete in the European Rugby Champion's Cup (ERCC). Since 2014 the tournament is organized as follows:
- 20 teams are split into 5 pools of 4 teams. During the pool stage, each team plays the 3 other teams of the pool twice (home/away games).
- Then the 8 best teams (the 5 pool leaders and 3 best runners-up) play the quarter-finals, such as:
- The best leader (#1) receive the third best runners-up(#8)
- The second best leader (#2) receive the second best runners-up(#7)
- The third best leader (#3) receive the best runners-up(#6)
- The fourth best leader (#4) receive the worst leader (#5)
- Then it is classical semi-finals and final.

Given the 4 teams of each group and the 60 games results of the pool-stage, your goal is to display the 4 quarter-finals.

INTRA-POOL RANKING RULES:
- Each team plays 6 games. A victory is worth 4 ranking-points, a draw 2 ranking-points, a loss 0 ranking-point. Each team can have up to 2 bonus ranking-points per game: 1 ranking-point for each team that scored at least 4 tries, 1 ranking-point for the losing team if they lost by a maximum of 7 game-points.
- In the event of a tie between two or more teams, the best-ranked team is selected using following tie-breakers:
- The team with the greatest number of ranking-points (including bonus points) from only games involving tied teams.
- If equal, the team with the best aggregate game-points difference from those games (game-points scored minus game-points conceded) (In this puzzle, you won't need more tiebreaker criteria).

INTER-POOL RANKING RULES:
To rank teams that are not in the same pool (in order to find who is qualified to the quarter-finals), the following criteria are used:
- Ranking in their pool (Leader, runner-up, third place, last place)
- Highest number of ranking-points in their pool
- If equal, best aggregate game-points difference (game-points scored minus game-points conceded) (In this puzzle, you won't need more tiebreaker criteria).
