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
tree.root = insertionRecursive(tree.root, 2); printInorderTraversal(tree.root); The tree is printed in the form of inorder traversal. BST Insertion Iterative To insert a Node iteratively in a BST tree, we will need to traverse the tree using two pointers. public static TreeNode insertionIt...
Searching a binary search tree is almost identical to inserting a new node except that we stop the traversal when we find the node we're looking for (during an insertion, this would indicate a duplicate node in the tree). If the node is not located, then we report this to the caller....

In subject area: Computer Science A Balanced Binary Tree is a type of binary search tree where the height of the tree is proportional to log base 2 of the number of elements it contains. This balanced structure ensures efficient searching, with elements being found by inspecting at most a fe...

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. ...
you've seen data arranged in atree. A tree is composed of a collection ofnodes, where each node has some associated data and a set ofchildren. A node's children are those nodes that appear immediately beneath the node itself. A node'sparentis the node immediately above it. A tree'sroot...
Given the root of a binary tree, return a deepest node. For example, in the following tree, return d.a / \ b c / d AnalysisFirst cut at finding depth of tree, carries a struct around. Second cut at finding depth of tree, completely recursive, returns deepest node. Third cut at ...
