A math problem
There are 8 venues, one as a team (this is just to look orderly. . )
The following is the arrangement of a group:
One person (marked as A) will be selected by drawing lots, and the remaining eight people will be eliminated and promoted. If there is a game of 15 minutes, there is only one player left in seven games (marked B), and then AB will play another game. A ***8 games, the time is 2 hours.
Eight groups compete in eight venues, so it doesn't matter.
Time to decide 8 winners: 2 hours.
After writing, I found that it should take (72-8) * 1 5/8 =120 minutes to destroy1person at a time.
In other words, if all the knockout rounds are played, the game for 8 people will take 2 hours, and the process will not affect = =.
Finally: only considering the time, it should be the fastest to play all the knockout rounds. But it's a bit unfair for players to play all the knockout rounds.
