Six class teams in grade six have a basketball match (elimination match). Six classes are divided into three groups. How should we draw lots? Urgent! ! ! ! !

In this way, in the scheme of 1, six classes are rotated first, and the two with the worst performance are eliminated, then four teams play against each other, and the loser wins the third place in the championship.

In the second scheme, six teams are eliminated first, three teams win the lottery, one team directly enters the championship and runner-up, and two teams lose the third place.

In the third scheme, the six teams catch each other first, and the three winning teams cycle, with the winner as the champion and the runner-up as the second.

There are many ways, depending on your time. Take it, hehe.
