算法和数据结构有什么区别？
算法（Algorithm）和数据结构（Data Structure）是计算机科学中两个关键概念，常常在设计和实现计算机程序时同时考虑。
它们的主要区别如下：
1. 定义和目的：算法是一种解决问题的方法或步骤的有序集合，描述了在给定输入的情况下如何产生所需输出。
它强调解决问题的方法和步骤。
数据结构是组织和存储数据的方式，提供了存储、访问和操作数据的方法。
它关注于数据的组织和操作。
2. 侧重点：算法的重点在于如何解决问题，并考虑算法的效率、正确性和优化。
它涉及到选择合适的控制结构、操作符、变量等，以及算法的复杂度分析。
数据结构的重点在于如何有效地组织和管理数据，以便提高程序的效率和性能。
3. 相互关系：算法和数据结构之间存在密切的关系。
