Five football teams play a single round robin game, and every two teams play a single round robin game. -:Five football teams play a single round robin game, one for every two teams. Each team played four games, and the third place scored 7 points, which tied with the first place. Then the other three games can only be two wins and one loss, because each team's score is different. The first place is tied with one game, and the other three games can only win, with a score of 3 * 3. In other words, if you win 2, 4 and 5, the second place can only be three wins and one loss, and the product of 3*3+0 =9 points. That is to say, if you win 3, 4 and 5, the interest of the third place is minus 2, the fourth place is minus 1, 2, 3, and the fifth place is minus 1, 2, 3.
Please give the compilation method for the five teams to play a single round robin, that is, the schedule-:To be fair, the game should be arranged in five rounds. The five teams (represented by 1-5 respectively) are all odd numbers, so some teams have to have a bye during the game (0 means empty, which means which team doesn't have to play when it meets 0). Here, the fixed-point counter-clockwise rotation method is adopted-that is, the team in the upper left corner is used as the axis, and everything else is used. The second round: 0-4, 5-3,1-2; The third round: 0-3, 4-2, 5-1; The fourth round: 0-2,3-1,4-5; Round 5: 0- 1, 2-5, 3-4. With this schedule, the rest time of each team is relatively balanced and fair. I wish your activity a complete success!

Those who exceed 16 will have five rounds, those who exceed 32 will have six rounds, and so on (and so on). One person will worship, and the population will be 1 minute. After each round, the next round will be ranked according to the points. The principle of arrangement is that you can't touch before, and you must start with the highest score, so as to ensure that people with the same score touch each other as much as possible. The party with the lowest score scores points after five rounds of worship: the party with the same score scores points progressively first, and then points progressively more than the opponent = points after the first round+points after the second round+.
