正确答案
解析
本题考查数据结构方面的基础知识。
线性表的查找有顺序查找、折半查找、分块查找方法。
其中,顺序查找方法的特点是算法非常简单,但效率较低.,因为它是用所给关键字与线性表中各元素的关键字逐个比较,直到成功或失败。
折半查找方法的优点是比较次数少,查找速度快,平均性能好;其缺点是要求待查表为有序表,且插入和删除困难。因此,折半查找方法适用于不经常变动而查找频繁的有序列表。
分块查找方法又称索引查找,它主要用于“分块有序”表的查找。所谓“分块有序”是指将线性表L(一维数组)分成m个子表(要求每个子表的长度相等),且第i+1个子表中的每一个项目均大于第i个子表中的所有项目。“分块有序”表应该包括线性表L本身和分块的索引表I。因此,分块查找的关键在于建立索引表I,其查找的平均长度介于顺序查找和折半查找之间。
