搜索二叉树的STL实现。包含树的前序、中序、后序遍历。-STL binary tree search implementation.

使用C++的STL数据结构实验，包括链表、八皇后、扩展洗车仿真、Binary Search Tree的平均树高等问题的实验-Using C++, STL data structure experiments, including lists, eight queens, extended car wash simulation, Binary Search Tree problems as the average tree experiment

一个有关stl操作的程序，实现了平衡二叉树，还有相关的数据结构，供大家学习-A related stl operating procedures, to achieve a balanced binary tree, as well as associated data structures for them to learn
