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。[1](Data structures are the way computers store and organize data. A data structure is a collection of data elements that exist in one or more specific relationships with each other. Typically, well chosen data structures can lead to higher running or storage efficiency. Data structures are often related to efficient retrieval algorithms and indexing techniques. [1])
