下列三个算法是关于“大规模数据集合中查找有无某些元素”问题的算法：针对一个“学生”数据表，如下示意，找出“成绩”为某一分数的所有学生。 【算法A1】 Start of algorithm A1 Step 1. 从数据表的第1条记录开始，直到其最后一条记录为止，读取每一条记录，做Step 2。 Step 2. 对每一条记录，判断成绩是否等于给定的分数：如果是，则输出；如果不是，则不输出。 End of algorithm A1 【算法A2】 Start of algorithm A2 Step 1. 从数据表的第1条记录开始，直到其最后一条记录为止，读取每一条记录，做Step 2和Step 3。 Step 2. 对每一条记录，判断成绩是否等于给定的分数：如果等于，则输出；如果不等于，则不输出。 Step 3. 判断该条记录的成绩是否小于给定的分数：如果不是，则继续；否则，退出循环，算法结束。 End of algorithm A2 【算法A3】 Start of algorithm A3 Step 1. 假设数据表的最大记录数是n，待查询区间的起始记录位置Start为1，终止记录位置Finish为n； Step 2. 计算中间记录位置I = (Start+Finish)/2，读取第I条记录。 Step 3. 判断第I条记录的成绩与给定查找分数： (3.1)如果是小于关系，则调整Finish = I-1；如果Start >Finish则结束，否则继续做Step 2； (3.2)如果是大于关系，则调整Start = I+1；如果Start>Finish则结束，否则继续做Step 2； (3.3)如果是等于关系，则输出，继续读取I周围所有的成绩与给定查找条件相等的记录并输出，直到所有相等记录查询输出完毕则算法结束。 End of algorithm A3 关于算法A3，下列说法正确的是_____。 /js/editor20150812/themes/default/images/spacer.gif
