Degenerate Binary Tree 5. Skewed Binary Tree A skewed binary tree is a pathological/degenerate tree in which the tree is either dominated by the left nodes or the right nodes. Thus, there are two types of skewed binary tree: left-skewed binary tree and right-skewed binary tree. Skewed Bi...

The parent nodes in a binary tree and the terminal nodes or the leaf nodes in a binary tree have a relation m = n - 1 (where m is the total number of the inner nodes or the parent nodes in a binary tree and n is the total number of the terminal nodes or leaf nodes in a bina...

The numberofnodesinthe tree is between1and10^4.The tree nodes will have distinct values between1and10^5. 分析 题意:将二叉搜索树平衡;每个节点的两个子树深度不超过一个节点,称为平衡。 一个笨办法是先获取原树的所有值,然后根据二叉搜索树的规则(二分法),重新建立起一颗平衡的二叉搜索树。

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 few nodes. ...
Binary Tree Postorder Traversal Given a binary tree, return thepostordertraversal of its nodes' values. For example: Given binary tree{1,#,2,3}, 1 \ 2 / 3 return[3,2,1]. Note:Recursive solution is trivial, could you do it iteratively?
