data-str-algo's Introduction

1. 什么是数据结构?

数据结构是计算机存储、组织数据的方式。数据结构是指相互之间存在一种或多种特定关系的数据元素的集合。通常情况下,精心选择的数据结构可以带来更高的运行或者存储效率。数据结构往往同高效的检索算法和索引技术有关。

2. 为什么我们需要数据结构?

数据是计算机科学当中最关键的实体,而数据结构则可以将数据以某种组织形式存储,因此,数据结构的价值不言而喻。 无论你以何种方式解决何种问题,你都需要处理数据——无论是涉及员工薪水、股票价格、购物清单,还是只是简单的电话簿问题。 数据需要根据不同的场景,按照特定的格式进行存储。有很多数据结构能够满足以不同格式存储数据的需求。

3. 常见的数据结构

数组

队列

链表

字典树(这是一种高效的树形结构,但值得单独说明)

散列表(哈希表)
