足球联赛采用单循环赛制，胜一场得3分，平局各得1分，负一场得0分，联赛排名以积分多者在前，当两队（或多队）积分相同时，则净胜球（即进球数与失球数之差）多者在前，若净胜球相同，则进球数多者在前，若仍相同，则抽签或踢附加赛决定名次（这在联赛结束后进行，联赛未结束则两队名次并列，本程序不做这方面要求）。试编一程序统计最近一轮比赛后，各队积分及排名。(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.)
