重点回顾
- 二分查找依赖数据的有序性，通过循环逐步缩减一半搜索区间来进行查找。它要求输入数据有序，且仅适用于数组或基于数组实现的数据结构。
- 暴力搜索通过遍历数据结构来定位数据。线性搜索适用于数组和链表，广度优先搜索和深度优先搜索适用于图和树。此类算法通用性好，无须对数据进行预处理，但时间复杂度
O(n)较高。 - 哈希查找、树查找和二分查找属于高效搜索方法，可在特定数据结构中快速定位目标元素。此类算法效率高，时间复杂度可达
O(\log n)甚至O(1)，但通常需要借助额外数据结构。 - 实际中，我们需要对数据规模、搜索性能要求、数据查询和更新频率等因素进行具体分析，从而选择合适的搜索方法。
- 线性搜索适用于小型或频繁更新的数据；二分查找适用于大型、排序的数据；哈希查找适用于对查询效率要求较高且无须范围查询的数据；树查找适用于需要维护顺序和支持范围查询的大型动态数据。
- 用哈希查找替换线性查找是一种常用的优化运行时间的策略，可将时间复杂度从
O(n)降至O(1)。
