二叉树(Binary Tree)是最简单的树形数据结构,然而却十分精妙。其衍生出各种算法,以致于占据了数据结构的半壁江山。STL中大名顶顶的关联容器——集合(set)、映射(map)便是使用二叉树实现。由于篇幅有限,此处仅作一般介绍(如果想要完全了解二叉树以及其衍生出的各种算法,恐怕要写8~10篇)。

In the above tree to delete node 6 with two children, we first find the inorder successor for that node to be deleted. We find the in-order successor by finding the minimum value in the right subtree. In the above case, the minimum value is 7 in the right subtree. We copy it to ...
github仓库存储地址:github.com/hlccd/goSTL 概述 二叉搜索树(Binary Search Tree)不同于之前使用的线性结构,它是一种通过离散的多个点以指针的形式连接起来的树形结构。 二叉树由一个根节点和根节点下属的多层次的子结点构成,任意一个结点最多只能拥有两个子结点,即左右子结点。基于此种特性,在实现二...
