1, What is a sort binary tree? If the nodes of a binary tree are one child larger or empty than itself and the other is smaller or empty than itself, such a binary tree is called a sorted binary tree, that is, BST. Then there are two situations. One is that the left child is small and the right child is large, and the other is that the left ch ...

Single chip microcomputer digital filtering algorithm Tip: you can add the directories of all articles in the series here. You need to add the directories manually For example, the first chapter is the use of pandas, an introduction to Python machine learning Tip: after writing the article, the directory can be generated automatically. For ...

Design pattern 1, Overview 1. Definition: a set of widely known, widely used, classified and catalogued reliable template code design experience summary. 2. Features: high cohesion and low coupling (also the ultimate goal) 3. Core idea: isolate changes and encapsulate changes 4. Significance: using design patterns can enhance the reusa ...

As the head of a city's emergency rescue team, you have a special national map. The map shows multiple scattered cities and some expressways connecting cities. The number of rescue teams in each city and the length of each expressway connecting the two cities are marked on the map. When other cities have emergency calls for you, your task is to ...

As the basic language of Java, c + + and other languages, c language inevitably has many disadvantages, such as too complex operation of memory, trouble in calling random numbers and so on. Here we help you sort out the generation and calling of the following random numbers ·rand function and its associated srand function   &nbsp ...

1, Basic elements of greedy algorithm As the name suggests, greedy algorithms always make the best choice at present. In other words, the greedy algorithm does not consider the overall optimization, and its choice is only the local optimal solution in a sense. The problems that can be solved by greedy algorithm generally have the follow ...

The sparsest set of prime numbers that satisfy Goldbach's conjecture is generated. There is also a simplest set generator that satisfies the Goldbach Conjecture Effect, which does not require a prime number. The Goldbach conjecture effect refers to the generation of a final set of numbers from a set M that belongs to an equidistant set M (or a ...

Strategy mode Definition: define a series of algorithms, encapsulate them one by one, and make them replaceable. This pattern allows the algorithm to vary independently of the customers using it. Advantages: (1) policy pattern provides a way to manage related algorithm families. The hierarchical structure of policy class defines an algorithm ...
