Getting better prizes in these competitions can help a lot in getting a job, whichACMThe series gets bronze medals and above in many of the big players (BATetc.) can be exempted from the machine test.
There is also the possibility of adding general test scores to help with awards and honors. You may get a higher score with these awards on the exam review.
In addition to getting awards in these tournaments, the odds are that the school will pay out prizes, ranging from a few hundred to a few thousand, and I've met a student who specializes in playing tournaments to get prizes thatFour years and $200,000 in total.。。。
And finally, promotion.
From the perspective of higher education, each year, graduate school or graduate school, in the re-examination stage generally have a machine test, this machine test is to do a few algorithmic problems in the specified time; some schools do not have a machine test, but also in the form of a written test out of a few algorithmic problems, so that the students handwritten.
How did I learn about algorithms?
Computing in this context is a generalized term that speaks to students in the broad category of computing, including computer science and technology, software engineering, cybersecurity, big data science, and so on.
So it's not hard to find that algorithmic brushing seems to have become the standard for computer students, which also explains why the ACM intensive selection is so hot in many universities, the better the computer the more so.
How to start is a big problem for many students, choose the wrong method is very easy to frequently fall down, around the wall, so that finally give up brushing.
When I first enrolled in my freshman year of college, I opened the Brush Problems website during one of the evening study sessions, chose the first problem and began to do it, looked at it for half an hour and did not have any ideas, then gave up this problem and did the second problem, and the result was that the ideas would not be a little bit of... This night to me to do autism. Later I realized that I came up to do is a very difficult topic in the algorithm of dynamic programming.
It was only with the help of my good friends in the same program that I gradually regained my confidence and figured out a way to learn algorithms.

Learn one/two programming languages
C and C++, these two languages are actually very similar, and C++ is an extended version of C. I learned C++ first, then C.
You can think about why I learned C++ first.
What I'm thinking is that since C++ is an extended version of C, then C++ will simplify the original complex operations, because technological advances generally make the original complex operations more convenient, then C++ must be cheaper to learn.How far did you learn?
The principle is to learn only the important, do not seek to learn all at once, many programming language courses can easily be several hundred episodes, which will be very discouraging. I always think that learning is a repeated process, after learning will forget is very normal, more use will not forget.
For both C++ and COnly basic grammar is requiredYou can just start without learning the classes of C++ and what comes after. When you learn, you can compare and contrast the similarities and differences between programming languages, you will find that programming languages are directly similar, when you learn one, and then learn the other will be very fast.
Where do I learn?
Most college computer science teachers read PPTs in class, so it's important to take the initiative and learn to go to bleeping college [manual slip].
Let's recommend a few courses that have a pretty good reputation. Of course if you find it easier to learn by reading a book rather than watching a video, there are plenty of books on the subject, so you can look them up on a search engine.

Data structures are the cornerstone of algorithms
This part is a bit more theory-heavy, and my introductory look at theData Structures for King's Road, this section needs to be well understood except for the external sort, which is important for learning the algorithms afterwards.

Start learning algorithms & brush up!
There are many ways to learn algorithms, if you have participated in the school's ACM intensive training, then there may be a senior's lecture course, in addition to the major platforms (such as force button, cowboys, Luogu) have their own algorithmic learning courses.
I used Acwing Algorithm Basics when I was studying, this course is considered to be my algorithm initiation course, but I have to say that it is actually very difficult to learn. Learning this course can not be rushed, because most of the algorithms we have not been exposed to, so we must be a topic a topic to gnaw down, each lesson of the knowledge points, you have to go back to find the relevant exercises to consolidate.
Most likely it will still feel abstract, and that's when I'll use a good search engine to find any blogs that talk about it better and help with understanding.
Where can I look for practice questions?
There are very many OJs (Online Judges) that offer a wide range of exercises as well as online assessments.
Before I give the addresses of these OJs, I need to remind that theDon't just go for quantity, just use a good two or three.
Part OJ:

I can dedicate another installment to these OJ differences if people want to know.

Participate in more competitions
It's a great way to improve by going to more tournaments and practicing with tournaments.
I used to think that I would have to learn the whole thing before entering the competition, but this is not the right way to think about it; by the time I have learned it all, the yellow flowers will be cold. In competitions you can find out your shortcomings and motivate yourself to improve.
Weekly or monthly contests are held for free on various platforms.
The better known ones are:
- leetcode weekly/bi-weekly tournaments
- Cowboys Weekly/Monthly/Challenges
- CodeforcesTournaments (irregular, one every few days)
- AtCodercompetition (sports etc)
- Acwing Game of the Week
There's also the Blue Bridge Cup, ladder tournaments, etc. that I mentioned above ......
In the end, behavior is better than words. Algorithm learning just look and do not practice will never learn, more learning and practice, diligence can make up for clumsiness, sink your heart to learn, on the way you have surpassed many, many people ......
I'll end by giving you a favorite quote to share with you: the best time to plant a tree is ten years ago, followed by now.
