## Data structure -- complete version of binary search tree (C + +)

When we search for an integer among n dynamic integers, there are several methods ① Using dynamic arrays, the average time complexity is O(n) ② Using an ordered dynamic array and binary search method, although its worst time complexity is only O(logn), its average time complexity of addition and depth is too high, which is O(n). ③ Using a link ...

## Analysis and java implementation of search related topics in binary tree in Leetcode

Analysis and java implementation of search related topics in binary tree in Leetcode In fact, there are some miscellaneous problems in this category. It is basically to find some or a specific value in the binary tree. There are many problems. We will summarize them through two or three articles, but generally speaking, it is basically BFS, whi ...

## Improvement of binary tree traversal algorithm (non recursive implementation)

Improvement of binary tree traversal algorithm The depth first traversal algorithms of binary tree are implemented by recursive functions, which is very inefficient. The reason is that the system calls a stack and does complex operations such as protecting the site and restoring the site, so that the traversal can be realized by very simple cod ...

## C++ binary search tree encoding and decoding

Serialize and deserialize binary search trees Title [leetcode449] Serialization is the process of converting a data structure or object into a series of bits so that it can be stored in a file or memory buffer, or transmitted over a network connection link for later reconstruction in the same or another computer environment. Design an algorithm ...

## (Java implementation) Binary tree --- threading

Overview Ordinary binary tree, with left and right child nodes, as shown below For a leaf node, its left and right child nodes are empty, and some non-leaf nodes may have only one child node, and each node will occupy a space, which will waste the created space. Threaded binary tree, exploiting these spaces Threaded Binary Tree Threaded B ...

## Clue binary tree

Clue binary tree This paper refers to the data structure of Dahua principle For a binary list with n nodes, each node has a pointer field pointing to the left and right children, so there are 2n pointer fields in total. The binary tree with n nodes has a total of n-1 branches, that is, there are 2n-(n-1)=n+1 empty finger needle fields. ...

## Data structure Chapter 6 (learning notes II (binary tree))

Binary tree Definition of binary tree A binary tree is a finite set of nodes (recursively defined) ① This set is either empty; ② Or it is composed of a root node and two disjoint binary trees called left subtree and right subtree. Five basic forms of binary tree Difference between binary tree and quadratic tree ① Different degrees A tre ...
