Implementation of linked list (complete code attached at the end of the article)
The concept and structure of linked lists A linked list is a non-continuous and non-sequential storage structure in terms of physical storage structure. The logical order of data elements is realized through the pointer link order in the linked list The sequence table we learned in the previous article is stored continuously For example: The […]

A completely decoupled time slice polling framework structure
1. The importance of program framework Many people, especially beginners, tend to think about writing bit by bit when writing code. They don’t have an overall plan at the beginning, which leads to more and more messy code later and constant bugs. In the end, the code seems to run without any problems (there may […]
The most complete collection of love codes in the history of C language and C++, with color flashing, character filling, and source code attached
The first type: red love code Go directly to the code: #include<stdio.h> #include<Windows.h> int main() {<!– –> system(” color 0c”);//Design program color printf(“It is a very happy thing to meet you, I love you!!!\\ “);//Print text \t float x,y,a;//define variables x,y,a \t for(y=1.5f;y>-1;y-=0.1f) {<!– –> for(x=-1.5f;x<1.5f;x + =.05f){<!– –> a=x*x + y*y-1; putchar(a*a*a-x*x*y*y*y<0.0f?’x’:’ ‘); } […]
SpringBoot3+Vue3+Mysql+Element Plus completes the database storage of blob type images, and the front end renders the base64 type images transmitted from the back end.
Foreword If your front-end and back-end separation project uses SpringBoot3 + Vue3 + Element Plus, and without OSS (object storage), use mysql to read and write images (may not be limited to images, to be tested). It took three days and after stepping on countless minefields, this function was finally completed. Presented to you. Complete […]

Caffe builds a complete set of squeezenet network projects
I used pytorch to build squeezenet before. I personally think pytorch is the best to use, but some projects require the caffe structure, so this article also uses caffe to build a squeezenet network. Data processing First, the data must be processed. Unlike pytorch, pytorch only needs to provide the directory where the data set […]
08 | How does MapReduce allow data to complete a journey?
In the last issue, we talked about the MapReduce programming model that divides the big data calculation process into two stages: Map and Reduce. Let’s review it first. In the Map stage, each data block is assigned a Map calculation task, and then all the map output keys are processed. Merge, the same Key and […]
