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)。
以bsTree二叉搜索树做接收者,向二叉树插入元素e,若不允许重复则对相等元素进行覆盖,如果二叉树为空则之间用根节点承载元素e,否则以根节点开始进行查找,不做平衡。 func(bs*bsTree)Insert(einterface{}){ifbs==nil{//创建一个允许插入重复值的二叉搜bs=New(true)}bs.mutex.Lock()ifbs.Empty(){//二叉...
