你看,首先就是,B树,不要与Binary tree或B+tree混淆。 B 树定义 B树是一种的平衡多路查找树,我们把树中结点最大的孩子数目称为B树的阶,通常记为m。 一棵m阶B树或为空树,或为满足如下特征的m叉树: 1)树中每个结点至多有m棵子树。(即至多含有m-1个关键字)(“两棵子树指针夹着一个关键字”)。 2)若...

In a previous version of the tool we used a linkedList as a data structure to store and access the subtitles, we later found that using a linked list might be the slower option specially in large sizes of data, due to this fact we decided to use a Sorted Binary search tree to gain ...
