I want to participate in ACM, can you tell me how to study?

In the case of ACM, you need to pay attention to a few points.

First of all: it's a memory problem, and the ACM score depends not only on whether your program can run, but also on your memory usage, and the less the better.

Second: you have to understand what each statement means and how to use it, because sometimes the question will limit what you want to use and what you can't use, which is a test for you.

Third: is the ability to think independently, ACM is different from ordinary team development, it is a thing that is completed independently by individuals, most of the competition is a person will make a question at speed, sometimes, when you train, you will think for a question, a person for a week, without asking classmates.

Therefore, it is OK to pay attention to the above points, and finally say that ACM is actually not necessary, and it will not help in the future.

Hehehe, if satisfied,

I don't know what level of your software has reached and therefore can't give you a good advice.

To participate in ACM, in general, you should have a relatively high level, have good system analysis skills, and be proficient in programming.

If you feel a little difficult, you can learn in advance and accumulate knowledge, and you can also learn well.

I can only talk about this, of course, only in general terms, but I hope it will help you.

Just start practicing the basic input and output, be familiar with this programming mode, and then go to OJ to do problems, first do simple, and then targeted practice algorithms, there is a lot of information on the Internet, in short, more practice is,

In fact, if you are ACM, you will take C or C++, in fact, the questions are simple, that is, you need strong logical thinking and mathematical knowledge, I participated in it last time, I have some questions and examples, you see if you need it.

Let's look at the introduction to algorithms first, the one of the Machinery Industry Press, it's quite thick, and the algorithms in it are all basic, go to HDU (or POJ (cut some water problems, which are topics with high AC number and AC rate.

Then look at Liu Rujia's algorithm art, collectively referred to as the "black book".

By the way, let's see if your school has an ACM training team, and contact us to see if there are any summer training camps and other activities, which our school has.

I've been doing ACM for 3 years, and most of them still learn by themselves, and I read books while cutting to the point, and I really don't know how to look at the solution report.

My ACM dedicated welcome exchange

I'm also participating.

I'm proficient in the basics.

It really does. Generally speaking, everyone is at the same level when simply learning algorithms to a certain extent, but if you want to go further, you need a very solid mathematical foundation, mathematics does not necessarily refer to number theory and combinatorial mathematics, more precisely, it should be an efficient way to analyze and think.

Therefore, it is easy to find the essence of the problem, you can produce a clear solution idea, and you can apply the algorithm you have learned, and the gap between the intermediate level acmer and the advanced level acmer is probably here, which is not something that time and experience can make up.

In fact, in international competitions, students from the Department of Mathematics often win gold and silver, and Lou Tiancheng won the first prize in the National Mathematics Competition in addition to poetry in high school, which is very revealing.

ACM candidates must be students who are pursuing a degree at their host school and have completed at least half of their studies. In addition, each team is allowed to have a maximum of one player with a bachelor's degree (that is, at least two of them have not yet obtained a bachelor's degree), and players who have already participated in two finals are not allowed to participate in regional competitions.

The selection is made several times and three times, and the school is registered. Each school has a team of judges who are in charge of a team of teachers, called "team leaders", who are responsible for the qualification of the players and designate or themselves as the coach of the team.

The competition is divided into two levels between teams of 3 people sent by various colleges and universities. Teams should first participate in the "Regional Competition", which takes place from September to November each year in various parts of the world. The team with the highest score in each regional competition automatically advances to the "finals" to be held in the United States in March of the following year, and other teams with the highest scores may also be invited to participate in the finals.
