How to make a basketball game map?

Take the badminton single elimination tournament as an example: there are 4 players in the upper half (1-4) and 4 players in the lower half (players 5-8).

The first seed player is fixed at the top of the upper half (serial number 1), the second seed player is fixed at the bottom of the lower half (serial number 8), and the third or fourth seed will draw lots to decide who will go to the top of the second 1/4 in the upper half and the bottom of the third 1/4 in the lower half (position 3 or 6 in the figure). Of course, the setting of seed players is also reasonable. Eight should have at most two seeded players, which is just a metaphor for eight people. (see photo)

If the number of participants is 7, then the first round is only 1. Of course, this bye-bye will give the championship the first seed (see photo). More than 8 people are 9, as shown in the figure of 9 people. There was only one game in the first round, and seven people had a bye in the first round. The first round is 5-6, the first round is eliminated 1 person, and the second round is. 10 and 1 1 are the same. It's just that the number of people who worship is stipulated, that is, the upper and lower parts of even numbers are evenly distributed, and the upper part of odd numbers has one more person than the lower part.

In a word, the arrangement of the tournament includes elimination, round robin, setting of seed players and drawing lots. It's so complicated that it can't be explained clearly in one or two sentences. The above is just a simple explanation. I hope it is useful to the landlord.
