但是,对于整个tree来说,有5个different structures: triangle (where the node has two leaves), left line (leaves are all left child), right line (leaves are all right child), left skewed line (leaves are left child, then right child), and right skewed line. 对于insertion来说,最复杂的是skew...

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)。
Given the root node of a binary search tree (BST) and a value to be inserted into the tree, insert the value into the BST. Return the root node of the BST after the insertion. It is guaranteed that the new value does not exist in the original BST. Note that there may exist multipl...
BST Insertion Recursively public static TreeNode insertionRecursive(TreeNode root, int value) { if (root == null) return new TreeNode(value); if (value < (int) root.data) { root.left = insertionRecursive(root.left, value); } else if (value > (int) root.data) { ...

Using the source code provided with this article is very easy. The following code illustrates the instantiation of a new binary tree, the insertion of data into the tree, and subsequent retrieval. The method insert() is used to insert new data, and the method findSymbol() is used to locat...
Invert a binary tree.For example, given the following tree:a / \ b c / \ / d e f should become:a / \ c b \ / \ f e d Code #1Code #2Code #3For attempt #1, I had it create a binary search tree of random-valued nodes so that the inversion is obvious. I wrote this one...
