① Press 1~32 to number 32 bits and take out 7 spaces. The remaining 25 yards were rowed by 25 athletes.
Note: the space should be evenly divided into upper and lower areas, where 1~ 16 is the upper area and 17~32 is the lower area. So the spaces are two, five, 12, 15, 18, 2 1, 3 1.
②32 yards in pairs. This empty pair is 1, 6, 1 1, 16, 17, 22, 32, and their first round is bye.
So the first round is 32 16, followed by 16 into 8, 8 into 4, 4 into 2, the champion.
