通用二叉搜索树，包含的算法有：输出广度优先遍历、前序、中序、后序遍历结果，按树的形状打印树，统计总节点数，统计叶子节点数，统计右节点数，计算树的高度，删除所有叶子节点，插入节点，查找节点，删除节点，由前序遍历结果和中序遍历结果生成树，由后序遍历结果和中序遍历结果生成树，检查该树是否平衡和完全平衡。-generic binary search tree contains the algorithm are : output breadth- first traversal, the former sequence, sequence, after the preorder, the shape of the tree by tree print, the total number of nodes statistics, statistics leaf nodes, the nodes to the right statistics to calculate tree height, remove all leaf nodes, insert nodes, the nodes you delete nodes from the former preorder results and the results of Spanning Tree preorder, After the preorder from the results and the results preorder spanning tree, check whether the tree balanced and complete balance.
