The time taken to insert or search for a specific item in a tree will be affected by a tree's depth. Deep trees take longer to search, and the insertion order into a tree can affect a tree's shape. A random insertion order will generally produce a more bushy and hence shallower tree...
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

You are given therootnode of a binary search tree (BST) and avalueto insert into the tree. Returnthe root node of the BST after the insertion. It is guaranteed that the new value does not exist in the original BST. Notice that there may exist multiple valid ways for the insertion, as...
Arranging Data in a Tree If you've ever looked at a genealogy table, or at the chain of command in a corporation, 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 ...
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. ...
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 ...
Thus, it is a data structure which is a type of self-balancing binary search tree. The balancing of the tree is not perfect but it is good enough to allow it to guarantee searching in O(log n) time, where n is the total number of elements in the tree. The insertion and deletion ...
