Football league matches adopt a single-cycle system, winning a game to get 3 points, draw to get 1 point, losing a game to get 0 points, league ranking to score more than the front, when two teams (or more teams) score the same, the net winner (that is, the difference between the number of goals and the number of goals) more than the front, if the net winner is the same, the number of goals before, if still the same. Then draw lots or play extra matches to determine the position (this is after the end of the league, the league is not over, the two teams are side by side, this procedure does not require this). Try compiling a program to rank and rank the teams after the last round of competition.
