I'm almost finished with my Binary Search Tree program. However, I'm stuck at deletion: removing a node with both left and right subtrees. The largest left value is promoted in the left subtree. It sometimes works, but does not always work the way it should be...

travel(tree.rchild) //对右孩子递归调用 } } 递归遍历二叉树可以参考递归函数的定义与实现部分的内容: 1递归函数 recursive function :输出正整数N各个位上的数字 2 还可以参考后面启动代码里面的其他已经实现的递归函数,二叉树的很多操作都是通过递归函数实现的。 例如,可以参考 print_in_order_recursive 的实现。
二叉搜索树(binary search tree)能够高效的进行插入, 查询, 删除某个元素,时间复杂度O(logn). 简单的实现方法例如以下. 代码: /* * main.cpp * * Created on: 2014.7.20 * Author: spike */ /*eclipse cdt, gcc 4.8.1*/ #include <stdio.h> ...
insertion binary search tree in C I've been stuck on the insertion part of the binary search tree. I get so confused with nested structs. The basic idea of this program is to create a bst that is able to hold names and double values which get stored by value (obviously)....
Binary Search (Recursive and Iterative) in C Program - Binary Search is a search algorithm that is used to find the position of an element (target value ) in a sorted array. The array should be sorted prior to applying a binary search. Binary search is a
