1 1 The basketball team requires a 5-day, 6-day or 7-day round robin. Please help me arrange it! I'd better arrange all three situations for me.

Play round robin. Single cycle ~ ~ means that each team will encounter 1 time, 1 1 team. Let's assume that A.B.C.D.E.F.G.H.I.J.K In order to cooperate with even teams, we will theoretically add another team: 0(A~K teams meet 0 teams, that is, the second round begins. In the table of each round, the position of team 0 remains unchanged, and the other A~K teams rotate counterclockwise 1 position, that is, the second round is: the third round is: the fourth round, and so on. . . . . . round 1 1:0-J 0-I 0-A K-I J-H B- Ka-H K-G C-J B- G A-F D-

If it is five days, it will be eleven games a day. Play for six days, nine games in the first five days and ten games on the sixth day. Seven days ago, seven games in six days and six games on the seventh day. (This arrangement requires more venues or the competition time is tight) It can be calculated by points.

What I want to say here is that the cycle has not eliminated the excitement, and there is luck in eliminating it. The lottery decided that one team must have a bye, and then after the game, six teams can play in the final, and then score 1-3 directly.

I hope I can help you. Please adopt!
