2、

The matching table above is for you to see clearly. If the number is directly 1-44,

The positions of the eight seeded players are 1 seed (1), 2 seeds (44), 3 seeds (23), 4 seeds (22), 5 seeds (12), 6 seeds (33), 7 seeds (34) and 8 seeds respectively.

The remaining bye positions are: 4, 5, 6, 15, 16, 17, 27, 28, 29, 38, 39 and 40 respectively.

3、

Number of games: number of participants-1, 44- 1=43.

Round: The number of participants is closest to (less than or equal to) the power of 2, and the number of participants is 44, which is closest to the power of 2 and the power of 6 (64), so the competition is 6 rounds.
