The 2d-tree adapts gracefully to the distribution of the points in the plane and it is often a better solution than the grid approach in which the plane is divided into equally sized squares, particularly when the points are not evenly distributed such as in geographic applications. As an ...
1、熟悉常见数据结构的概念,比如说数组、堆栈、链表、哈希表等。 2、了解常用数据结构之间的差异,比如说 ArrayList 和 LinkedList,我在之前的文章中有详细说明过,可以点击链接去查看下。 3、关注常用数据结构的外围算法,比如说如何对 List 和 Map 进行查找。 4、关注数据结构使用中容易出错的地方,比如说线程是否安全...
