AComplete all n-1 scans 完成全部n-1趟扫描交换
BThe number of scan conversions completed = The number of scan switching parameters for the actual element exchange + 1 完成的扫描交换趟数 = 实际发生元素交换的扫描交换趟数 + 1
CThe number of scan conversions completed = The number of scan switchings that actually took place for element exchange 完成的扫描交换趟数 = 实际发生元素交换的扫描交换趟数
DComplete (n - 1) / 2 scan exchange 完成 (n - 1) / 2趟扫描交换
